Detailed Implementation

[0009] Compositions (e.g., coatings) comprising fingerprint-inhibiting materials, as well as related articles, methods, and kits, are generally described. In some embodiments, the coating comprises a fingerprint-inhibiting material configured to reduce, inhibit, and / or prevent fingerprints from appearing on a surface to which the coating is disposed. In some embodiments, the fingerprint-inhibiting properties of the coating (e.g., an anti-fingerprint coating) can be provided by a silane compound comprising a polysiloxane, which reduces the surface energy of the surface on which the coating is disposed and makes the coating hydrophobic and / or oleophobic. According to some embodiments, in addition to providing anti-fingerprint properties, the coating may be chemically inert, mechanically robust, optically transparent, and / or smooth.

[0010] Advantageously, the compositions (e.g., coatings), articles, methods, and kits described herein can have beneficial properties compared to conventional coatings and related methods. In some embodiments, for example, the coating is non-fluorinated, thereby eliminating problems associated with toxicity and / or bioaccumulation, problems associated with conventional coatings containing anti-fingerprint materials including fluorinated components. Furthermore, conventional coatings including fluorinated components are synthesized and / or processed using fluorinated solvents. The non-fluorinated coatings described herein advantageously avoid the use of such fluorinated solvents, thus reducing fluorinated greenhouse gas emissions.

[0011] According to some embodiments, the silane compound comprises a polysiloxane (e.g., a repeating unit of ((R)2-Si-O)). In some embodiments, at least a portion of the silane compound may be functionalized with one or more hydrolyzable portions. In some embodiments, the hydrolyzable portion may react with a hydrolyzing agent to provide a hydrolysis product of the silane compound. In some embodiments, the hydrolysis product of the silane compound may have improved durability compared to an unhydrolyzed silane compound that is otherwise equivalent. According to some embodiments, the silane compound may be hydrolyzed before, during, and / or after applying a composition comprising the silane compound to at least a portion of at least one surface of a substrate, as explained in more detail herein. In some embodiments, the hydrolysis product of the silane compound may exhibit enhanced adhesion to the substrate compared to an unhydrolyzed silane compound that is otherwise equivalent.

[0012] In some embodiments, the silane compound comprises an ether (e.g., the ROR moiety) or a thioether (e.g., the RSR moiety). In some embodiments, the ether and / or thioether may comprise a long alkyl chain, which advantageously provides the silane compound with increased hydrophobicity compared to a silane compound that does not contain a long alkyl chain but is otherwise equivalent.

[0013] According to some embodiments, silane compounds can be synthesized by reacting two or more precursor silane compounds. In some embodiments, the reaction of two or more precursor silane compounds can provide a silane compound reaction product having a favorable large number of hydrolyzable groups that enhance the adhesion of the silane compound to a substrate, as explained in more detail herein. In some embodiments, for example, the silane compound can be synthesized by reacting a first precursor silane compound comprising a siloxane (e.g., a monomer, polymer, copolymer) with a second precursor silane compound (e.g., a monomer, polymer, copolymer) in the presence of a catalyst and heat. According to some embodiments, the resulting reaction product can be deposited onto at least a portion of at least one surface of a substrate. In some embodiments, for example, the composition can be sprayed (e.g., sprayed) onto at least a portion of at least one surface of a substrate. According to some embodiments, after depositing the composition, the composition can be heated (e.g., thermocure) to provide a coating.

[0014] The composition (e.g., coating) can be used in any of a variety of suitable applications. In some embodiments, for example, the composition can be applied to a substrate, such as glass, plastic, metal and / or metal oxide, for example, for electronic displays, such as, but not limited to, mobile phone screens, computer monitors, television screens, touch screens, electrical appliances and / or head-up displays. In some embodiments, the coating can be applied to a substrate used in transportation vehicles (e.g., automobiles, aircraft, etc.) and / or building equipment.

[0015] Turning to the accompanying drawings, specific non-limiting embodiments are described in more detail. It should be understood that the various systems, components, features, and methods described with respect to these embodiments can be used individually and / or in any desired combination, as this disclosure is not limited to the specific embodiments described herein.

[0016] Figure 1 A schematic diagram of an exemplary article of manufacture according to certain embodiments is shown. In some embodiments, for example, article 100 includes a substrate 110 having at least one surface 120. Suitable substrate materials are explained in further detail herein.

[0017] According to some embodiments, composition 130 may be disposed on at least a portion of at least one surface 120, such that composition 130 coats at least a portion of at least one surface 120. In some embodiments, composition 130 comprises a fingerprint-inhibiting material, which will be explained in further detail herein.

[0018] Although the composition 130 of the coated surface 120 is described as a smooth layer of uniform thickness, those skilled in the art will understand that this is for illustrative purposes only, and that, according to some embodiments, the thickness of the composition of the coated surface may have a specific roughness and / or the thickness may vary. However, in some embodiments, the composition of the coated surface may have a relatively uniform thickness (e.g., within 10% of the total thickness) over at least a majority of the substrate surface (e.g., greater than or equal to 75% of the surface area of ​​the substrate surface on which the composition is disposed).

[0019] In some embodiments, the composition coating the surface may have any of a variety of suitable thicknesses. (Reference) Figure 1For example, a composition 130 coating at least a portion of at least one surface 120 may have a thickness 132. In some embodiments, the average thickness of the composition coating the surface is greater than or equal to 5 nm, greater than or equal to 10 nm, greater than or equal to 20 nm, greater than or equal to 30 nm, greater than or equal to 40 nm, greater than or equal to 50 nm, greater than or equal to 60 nm, greater than or equal to 70 nm, greater than or equal to 80 nm, or greater than or equal to 90 nm.

Combinations of the above ranges are possible (e.g., the composition coating the surface has an average thickness greater than or equal to 5 nm and less than or equal to 100 nm, or greater than or equal to 40 nm and less than or equal to 60 nm). Other ranges are also possible. In some embodiments, the average thickness of the composition coated on the surface can be determined by elliptic photometry.

[0020] In some embodiments, the composition (e.g., a coating) comprises a fingerprint-suppressing material. According to some embodiments, the fingerprint-suppressing material is non-fluorinated, such that it does not contain any fluorine (F) atoms.

[0021] The composition (e.g., coating) may contain fingerprint-inhibiting material in any of a variety of suitable amounts. In some embodiments, for example, the composition contains fingerprint-inhibiting material in amounts greater than or equal to 0.1 wt.%, greater than or equal to 1 wt.%, greater than or equal to 5 wt.%, greater than or equal to 10 wt.%, greater than or equal to 20 wt.%, greater than or equal to 30 wt.%, greater than or equal to 40 wt.%, greater than or equal to 50 wt.%, greater than or equal to 60 wt.%, greater than or equal to 70 wt.%, greater than or equal to 80 wt.%, or greater than or equal to 90 wt.%, based on the total weight of the composition. In some embodiments, the composition comprises fingerprint-inhibiting material in amounts less than or equal to 100 wt.%, less than or equal to 90 wt.%, less than or equal to 80 wt.%, less than or equal to 70 wt.%, less than or equal to 60 wt.%, less than or equal to 50 wt.%, less than or equal to 40 wt.%, less than or equal to 30 wt.%, less than or equal to 20 wt.%, less than or equal to 10 wt.%, less than or equal to 5 wt.%, or less than or equal to 1 wt.%. Combinations of the above ranges are possible (e.g., the composition comprises fingerprint-inhibiting material in amounts greater than or equal to 0.1 wt.% and less than or equal to 100 wt.%, or greater than or equal to 40 wt.% and less than or equal to 60 wt.%, based on the total weight of the composition). Other ranges are also possible.

[0022] According to some embodiments, the fingerprint-suppressing material comprises a silane compound (e.g., a non-fluorinated silane compound). According to some embodiments, the silane compound comprises a polysiloxane. For example, in some embodiments, the silane compound comprises repeating units of ((R)₂-Si-O). In some embodiments, the silane compound comprising the polysiloxane may be linear. In other embodiments, the silane compound comprising the polysiloxane may be branched.

[0023] According to some embodiments, the silane compound may contain one or more hydrolyzable moieties. In some embodiments, examples of suitable hydrolyzable moieties include, but are not limited to, alkoxy moieties (e.g., -OR moieties), hydroxyl (-OH) moieties, halogen moieties (e.g., -Cl moieties, -Br moieties, and -I moieties), amines, etc. (e.g., other leaving groups). Other hydrolyzable moieties are also possible. According to some embodiments, the silane compound may contain one or more hydrolyzable moieties (e.g., hydrolysis products of the silane compound). In some embodiments, for example, one or more hydrolyzable moieties may react with a hydrolyzing agent, as explained in more detail below.

[0024] According to some embodiments, the polysiloxane comprises one or more hydrophobic portions. Advantageously, the one or more hydrophobic portions can reduce the total surface energy of the composition (e.g., coating) containing the polysiloxane. In some embodiments, for example, the hydrophobic portions include methylsilyl (-Si(CH3)) portions, dimethylsilyl (-Si(CH3)2) portions, trimethylsilyl (-Si(CH3)3) portions, methylsiloxy (-Si(CH3)O) portions, dimethylsiloxy (-Si(CH3)2O) portions, trimethylsiloxy (-Si(CH3)3O) portions, and alkylene portions (e.g., -(CH2)). n -partial), subalkenyl moiety (e.g., -(C n H 2n-2 ) n -partial), ynyne moiety (e.g., -(C n H 2n-4 ) n - Partial), etc. Other hydrophobic components are also possible.

[0025] Silane compounds may have any of a variety of suitable molecular weights. In some embodiments, for example, the molecular weight of the silane compound is greater than or equal to 500 Da, greater than or equal to 1,000 Da, greater than or equal to 5,000 Da, greater than or equal to 10,000 Da, greater than or equal to 20,000 Da, greater than or equal to 30,000 Da, greater than or equal to 40,000 Da, greater than or equal to 50,000 Da, greater than or equal to 75,000 Da, greater than or equal to 100,000 Da, greater than or equal to 200,000 Da, greater than or equal to 300,000 Da, or greater than or equal to 400,000 Da. In some embodiments, the molecular weight of the silane compound is less than or equal to 500,000 Da, less than or equal to 400,000 Da, less than or equal to 300,000 Da, less than or equal to 200,000 Da, less than or equal to 100,000 Da, less than or equal to 50,000 Da, less than or equal to 40,000 Da, less than or equal to 30,000 Da, less than or equal to 20,000 Da, less than or equal to 10,000 Da, less than or equal to 5,000 Da, or less than or equal to 1,000 Da. Combinations of the above ranges are possible (e.g., the silane compound has a molecular weight greater than or equal to 500 Da and less than or equal to 500,000 Da, or greater than or equal to 10,000 Da and less than or equal to 20,000 Da). Other ranges are also possible. In some embodiments, the molecular weight of the silane compound is determined by gel permeation chromatography (GPC).

[0026] According to some embodiments, the molecular weight of the silane compound can be advantageously adjusted for a specific application. For example, in some embodiments, a composition containing a silane compound with a lower molecular weight may have increased optical transparency (e.g., percentage optical transmittance) compared to a composition containing a silane compound with a higher molecular weight. In some embodiments, a composition containing a silane compound with a higher molecular weight may have increased hydrophobicity compared to a composition containing a silane compound with a lower molecular weight. Therefore, according to some embodiments, a composition containing a silane compound with a lower molecular weight can be used in applications where a higher percentage optical transmittance is desired, while a composition containing a silane compound with a higher molecular weight can be used in applications where a higher hydrophobicity is desired.

[0094] In some embodiments, step 202 of method 200 includes providing a substrate 110 comprising at least one surface 120. According to some embodiments, the method includes activating at least a portion of the substrate. In some embodiments, the substrate is activated, for example, by exposing it to plasma of an inert gas such as, but not limited to, Ar, Ne, He, N2, O2, H2O, and / or mixtures thereof. In some embodiments, the substrate is activated by mechanically treating the surface with a metal oxide or acid etching (e.g., with hydrofluoric acid or hydrochloric acid). It is not desirable to be bound by theory, but due to activation at the substrate, the density of hydroxyl (-OH) moieties on the substrate surface increases, thereby promoting the fixation (e.g., bonding) of silane compounds on the substrate surface, as explained in more detail herein.

[0095] According to some embodiments, step 204 of method 200 includes setting (e.g., depositing) composition 130 (e.g., fingerprint inhibiting material) on at least a portion of at least one surface 120 of substrate 110 such that composition 130 coats at least a portion of at least one surface 120 of substrate 110. In some embodiments, as explained in more detail herein, due to setting the composition on at least a portion of at least one surface of substrate, the silane compound of the composition can be fixed (e.g., bonded) to the surface of substrate.

[0096] The deposition composition (e.g., a fingerprint-inhibiting material) may include any of a variety of suitable deposition methods. According to certain embodiments, the deposition composition includes, for example, sputtering (e.g., spraying), spin coating (e.g., spin coating), dipping (dip coating), wiping, chemical vapor deposition (CVD), and / or physical vapor deposition (PVD).

[0097] Although not shown in the figures, compositions containing fingerprint-inhibiting materials may be reacted with one or more additional components prior to deposition onto at least a portion of at least one surface of a substrate. In some embodiments, for example, the fingerprint-inhibiting material may be reacted with one or more hydrolyzing agents and / or adhesion promoters prior to deposition onto at least a portion of at least one surface of a substrate. In some embodiments where the composition containing fingerprint-inhibiting material is reacted with one or more hydrolyzing agents prior to deposition onto at least a portion of at least one surface of a substrate, the one or more hydrolyzing agents may hydrolyze the silane compound of the composition (e.g., thereby providing a hydrolysis product of the silane compound) prior to deposition onto at least a portion of at least one surface of the substrate.

[0098] Although not shown in the figures, according to certain embodiments, a composition comprising a fingerprint-inhibiting material and one or more additional components may be deposited onto at least a portion of at least one surface of a substrate. In some embodiments, for example, a composition comprising a mixture of a fingerprint-inhibiting material and one or more hydrolyzing agents and / or adhesion promoters may be deposited onto at least a portion of at least one surface of a substrate. In some embodiments where the composition comprises a mixture of a fingerprint-inhibiting material and one or more hydrolyzing agents deposited onto at least a portion of at least one surface of the substrate, the one or more hydrolyzing agents may hydrolyze the silane compound of the composition (e.g., thereby providing a hydrolysis product of the silane compound) while the composition is deposited onto at least a portion of at least one surface of the substrate. In other embodiments where the composition comprises a mixture of a fingerprint-inhibiting material and one or more hydrolyzing agents deposited onto at least a portion of at least one surface of the substrate, the one or more hydrolyzing agents may hydrolyze the silane compound of the composition after the composition has been deposited onto at least a portion of at least one surface of the substrate (e.g., thereby providing a hydrolysis product of the silane compound).

[0099] According to some embodiments, the coating substrate may include a composition (e.g., a fingerprint-inhibiting material) heated (e.g., cured, annealed) and disposed on at least a portion of at least one surface of the substrate, thereby providing article 100 in step 206.

[0100] The composition (e.g., a fingerprint-inhibiting material) can be heated (e.g., cured) to any variety of suitable temperatures. In some embodiments, the composition is heated (e.g., cured) to temperatures greater than or equal to 25°C, greater than or equal to 50°C, greater than or equal to 75°C, greater than or equal to 100°C, greater than or equal to 110°C, greater than or equal to 120°C, greater than or equal to 130°C, or greater than or equal to 140°C. In some embodiments, the composition is heated (e.g., cured) to temperatures less than or equal to 150°C, less than or equal to 140°C, less than or equal to 130°C, less than or equal to 120°C, less than or equal to 110°C, less than or equal to 100°C, less than or equal to 75°C, or less than or equal to 50°C. Combinations of the above ranges are possible (e.g., heating the composition to temperatures greater than or equal to 25°C and less than or equal to 150°C, or greater than or equal to 120°C and less than or equal to 140°C). Other ranges are also possible.

[0101] The composition (e.g., a fingerprint-inhibiting material) can be heated to any of the above-mentioned temperatures for any variety of suitable times. In some embodiments, for example, the composition is heated (e.g., cured) for more than or equal to 1 minute, more than or equal to 30 minutes, more than or equal to 1 hour, more than or equal to 5 hours, more than or equal to 10 hours, more than or equal to 24 hours, more than or equal to 48 hours, or more than or equal to 72 hours. In some embodiments, the composition is heated (e.g., cured) for less than or equal to 96 hours, less than or equal to 72 hours, less than or equal to 48 hours, less than or equal to 24 hours, less than or equal to 10 hours, less than or equal to 5 hours, less than or equal to 1 hour, or less than or equal to 30 minutes. Combinations of the above ranges are possible (e.g., heating the composition for more than or equal to 1 minute and less than or equal to 96 hours, heating the composition for more than or equal to 10 hours and less than or equal to 24 hours). Other ranges are also possible.

[0102] In some embodiments, the amount of time for heating the composition depends on the temperature at which the composition is heated. In some embodiments, for example, a higher composition heating temperature (e.g., greater than or equal to 100°C) is associated with a shorter composition heating time (e.g., less than or equal to 1 hour). In some embodiments, a lower composition heating temperature (e.g., less than or equal to 75°C) is associated with a longer composition heating time (e.g., greater than or equal to 5 hours).

[0103] In some embodiments, the amount of time and / or the temperature at which the composition is heated depends on the substrate on which the composition is disposed (e.g., deposited). In some embodiments, for example, higher composition heating temperatures (e.g., greater than or equal to 100°C) and shorter composition heating times (e.g., less than or equal to 1 hour) are associated with compositions disposed (e.g., deposited) on a glass substrate. In some embodiments, lower composition heating temperatures (e.g., less than or equal to 75°C) and longer composition heating times (e.g., greater than or equal to 5 hours) are associated with compositions disposed (e.g., deposited) on a polymer (e.g., plastic) substrate.

[0104] According to certain embodiments, the coating containing the fingerprint-inhibiting material (e.g., an anti-fingerprint coating) may be hydrophobic. The coating containing the fingerprint-inhibiting material (e.g., an anti-fingerprint coating) may have any variety of suitable water contact angles. In some embodiments, for example, the water contact angle of the coating containing the fingerprint-inhibiting material is greater than or equal to 90°. o ≥95 o ≥100 o ≥105 o 110 or greater o ≥115o 120 or greater o ≥125 o ≥130 o ≥135 o ≥140 o ≥145 o ≥150 o ≥155 o ≥160 o ≥165 o ≥170 o or greater than or equal to 175 o In some embodiments, the water contact angle of the coating containing the fingerprint-inhibiting material is less than or equal to 180 degrees. o Less than or equal to 175 o Less than or equal to 170 o Less than or equal to 165 o Less than or equal to 160 o Less than or equal to 155 o Less than or equal to 150 o Less than or equal to 145 o Less than or equal to 140 o Less than or equal to 135 o Less than or equal to 130 o Less than or equal to 125 o Less than or equal to 120 o Less than or equal to 115 o Less than or equal to 110 o Less than or equal to 100 o or less than or equal to 95 o Combinations of the above ranges are possible (e.g., a coating containing fingerprint-inhibiting material with a value greater than or equal to 90). o And less than or equal to 180 o or greater than or equal to 130 o And less than or equal to 140 o (Water contact angle). Other ranges are also possible. In some embodiments, the water contact angle of the coating containing the fingerprint-inhibiting material is determined by a goniometer.

[0105] In some embodiments, the coating containing the fingerprint-inhibiting material (e.g., an anti-fingerprint coating) may be oleophobic. The coating containing the fingerprint-inhibiting material (e.g., an anti-fingerprint coating) may have any suitable diiodomethane contact angle. In some embodiments, for example, the diiodomethane contact angle of the coating containing the fingerprint-inhibiting material is greater than or equal to 55°. o60 or greater o 65 or greater o 70 or greater o ≥75 o ≥80 o ≥85 o ≥90 o ≥95 o ≥100 o ≥105 o 110 or greater o ≥115 o 120 or greater o ≥125 o ≥130 o ≥135 o ≥140 o ≥145 o ≥150 o ≥155 o ≥160 o ≥165 o ≥170 o or greater than or equal to 175 o In some embodiments, the diiodomethane contact angle of the coating containing the fingerprint-inhibiting material is less than or equal to 180°. o Less than or equal to 175 o Less than or equal to 170 o Less than or equal to 165 o Less than or equal to 160 o Less than or equal to 155 o Less than or equal to 150 o Less than or equal to 145 o Less than or equal to 140 o Less than or equal to 135 o Less than or equal to 130 o Less than or equal to 125 o Less than or equal to 120 o Less than or equal to 115 o Less than or equal to 110 o Less than or equal to 105 o Less than or equal to 100 o Less than or equal to 95 o Less than or equal to 90 o Less than or equal to 85 o Less than or equal to 80o Less than or equal to 75 o Less than or equal to 70 o Less than or equal to 65 o or less than or equal to 60 o Combinations of the above ranges are possible (e.g., a coating containing fingerprint-inhibiting material with a value greater than or equal to 55). o And less than or equal to 180 o or greater than or equal to 110 o And less than or equal to 120 o (Diiodomethane contact angle). Other ranges are also possible. In some embodiments, the diiodomethane contact angle of the coating containing the fingerprint-inhibiting material is measured using a goniometer.

[0106] Conventional substrates and coatings applied thereto are susceptible to mechanical abrasion, which over time reduces, wears away, and / or diminishes coating thickness, transparency, and / or coating effectiveness. Abrasion occurs during user handling of the substrate, such as by rubbing with a cloth to remove unwanted material (e.g., removing dirt), which is periodically necessary to restore satisfactory visibility of the coating. In some embodiments, reduction may stem from exposure to ultraviolet radiation, heat, cold, chemicals, salt and / or other corrosive substances, dirt, other abrasive materials and / or other environmental elements, conditions, and / or materials.

[0107] In some embodiments, the coating (e.g., an anti-fingerprint coating) can be durable. In some embodiments, the coating exhibits specific abrasion resistance, for example, measured by water contact angle and / or diiodomethane contact angle after a certain number of abrasion cycles. In some embodiments, the abrasion method is based on a linear abrasion meter apparatus using an eraser. In some embodiments, the abrasion method is based on ASTM D1044.

[0108] According to certain embodiments, the water contact angle of the coating (e.g., an anti-fingerprint coating) can decrease by any various suitable percentage after multiple linear wear cycles.

[0127] Example 1 The following examples describe the synthesis and characterization of coatings containing silane compounds, which include polysiloxanes.

[0128] Linear bifunctional silane-terminated polydimethylsiloxanes, namely Silmer TMS Di-10 (1,100 g / mol), Silmer TMS Di-50 (3,800 g / mol), and Silmer TMS Di-400 (30,000 g / mol), were purchased from Siltech Corporation. Anhydrous ethanol (94–96%) and isopropanol (98+%) were purchased from Alfa Aesar. Nitric acid (70%) was purchased from Sigma-Aldrich. All materials were used as is without further purification.

[0129] TMS Di-10, TMS Di-50, and TMS Di-400 were dissolved in ethanol / isopropanol, respectively, and then 70% nitric acid was added to each solution. The solutions were then sprayed onto a glass substrate. The coated samples were then placed in an oven at 120°C. o Heat-cur at C for 24 hours. Then, allow the coated sample to cool to room temperature.

[0130] The water contact angle and diiodomethane contact angle of the coatings were measured using a goniometer, and the durability of the coatings was evaluated by eraser abrasion using a linear abrasion apparatus. The water contact angles of TMS Di-10, TMS Di-50, and TMS Di-400 before and after 3,000 linear eraser abrasion cycles are shown below. Figure 3A As shown. The diiodomethane contact angles of TMS Di-10, TMS Di-50, and TMS Di-400 before and after 3,000 linear wear cycles of the eraser are shown in the figure. Figure 3B In the medium, the initial water contact angle and diiodomethane contact angle increased with increasing molecular weight. In contrast, the water contact angle after 3,000 wear cycles decreased with increasing molecular weight, while the diiodomethane contact angle after 3,000 wear cycles remained essentially constant with increasing molecular weight.

[0133] TMS Di-10 was added to a reactor open to ambient atmosphere, followed by the addition of 0.1 wt.% DBTDL relative to the total weight of TMS Di-10. The reaction mixture was stirred for 23 hours.

[0134] After the reaction was completed, the reaction products were analyzed by GPC. Figure 4 The molecular weight distribution of the reaction products of TMS Di-10 and DBTDL is compared with that of TMS Di-10. The molecular weight distribution of the reaction products of TMS Di-10 and DBTDL is found to be higher than that of TMS Di-10, indicating the hydrolytic condensation of the alkoxysilane moiety.

[0135] The reaction product of TMS Di-10 and DBTDL was dissolved in isopropanol and sprayed onto a glass substrate. The coated sample was then subjected to a 120°C test. o Heat cure at C for 15-30 minutes. Then, allow the coated sample to cool to room temperature.

[0136] The water contact angle and diiodomethane contact angle of the coating were measured using a goniometer, and the coating durability was evaluated by rubber abrasion using a linear abrasion apparatus. The water contact angles of the reaction products of TMS Di-10 and DBTDL before and after 3,000 rubber abrasion cycles are shown below, compared to TMS Di-10. Figure 5A The diiodomethane contact angles of the reaction products of TMS Di-10 and DBTDL before and after 3,000 linear rubber-rubber wear cycles are shown in the figure. Figure 5B In the middle, as the crosslinking density of the material increases, the initial water contact angle and diiodomethane contact angle increase by ≤10°. o Since the water contact angle and diiodomethane contact angle did not change significantly after 3,000 abrasion cycles, no significant impact was observed on the coating's durability.

[0140] The water contact angle and diiodomethane contact angle of the coating were measured using a goniometer, and the coating durability was evaluated by eraser abrasion using a linear abrasion apparatus. The water contact angles of the reaction products of TMS-Di-10 and DBTDL at a weight ratio of 90:10, before and after 3,000 linear eraser abrasion cycles, compared to TMS Di-10, are shown below. Figure 6A The diiodomethane contact angles of the reaction products of TMS-Di 10 and DBTDL at a weight ratio of 90:10, before and after 3,000 linear eraser wear cycles, compared to TMS Di-10, are shown in the figure. Figure 6B In comparison, the initial water contact angle of the reaction products of TMS Di-10 and DBTDL at a weight ratio of 90:10 increased by ≤10° compared to TMS Di-10.o The coating's durability is slightly improved because, after 3,000 abrasion cycles, the water contact angle and diiodomethane contact angle are ≤5°. o Improvements.

[0169] While several embodiments of the invention have been described and illustrated herein, those skilled in the art will readily conceive of various other means and / or structures for performing functions and / or obtaining results and / or one or more advantages described herein, and each of these variations and / or modifications is considered to be within the scope of the invention. More generally, those skilled in the art will readily understand that all parameters, dimensions, materials, and configurations described herein are exemplary, and actual parameters, dimensions, materials, and / or configurations will depend on one or more specific applications using the teachings of the invention. Those skilled in the art will recognize or be able to determine many equivalents of the specific embodiments of the invention described herein using only conventional experimentation. Therefore, it should be understood that the foregoing embodiments are presented by way of example only, and that the invention may be practiced in ways other than those specifically described and claimed within the scope of the appended claims and their equivalents. The invention relates to each individual feature, system, article, material, and / or method described herein. Furthermore, any combination of two or more such features, systems, articles, materials, and / or methods, provided that such features, systems, articles, materials, and / or methods do not contradict each other, is included within the scope of the invention.

[0170] In the event of conflicting and / or inconsistent disclosures in this specification and other documents incorporated by reference, this specification shall prevail. If two or more documents incorporated by reference contain disclosures that conflict and / or are inconsistent with each other, the document with the later effective date shall prevail.

[0171] All definitions defined and used herein should be understood to take precedence over dictionary definitions, definitions in referenced literature, and / or the general meaning of the defined terms.

[0172] Unless expressly indicated to the contrary, the indefinite articles “a” and “an” as used herein in the specification and claims shall be understood to mean “at least one”. As used herein in the specification and claims, the phrase “and / or” should be understood to mean “any one or both” of the elements so connected, that is, an element present in some cases as a conjunction and in others as a disjunctive. In addition to the elements specifically identified by the “and / or” statement, other elements may optionally be present, whether related to or unrelated to those specifically identified, unless explicitly stated otherwise. Thus, as a non-limiting example, when used in conjunction with open-ended language such as “comprising,” the reference to “A and / or B” can be understood to mean, in one embodiment, A without B (optionally including elements other than B); in another embodiment, B without A (optionally including elements other than A); in yet another embodiment, both A and B (optionally including other elements); and so on.

[0173] As used herein in the specification and claims, “or” should be understood to have the same meaning as “and / or” as defined above. For example, when separating items in a list of items, “or” and “and / or” should be interpreted as inclusive, that is, including multiple elements or at least one of a list of elements, but also including more than one, and optionally, other unlisted items. Only when explicitly indicating the opposite, such as “only one of…” or “exactly one of…”, or when used in the claims, “consisting of…” will refer to including multiple elements or only one of a list of elements. Generally, when preceded by exclusive terms such as “any,” “one of,” “only one of,” or “exactly one of,” the term “or” as used herein should only be interpreted as indicating an exclusive alternative (i.e., “one or the other but not both”). When used in the claims, “consisting substantially of…” should have its ordinary meaning as used in the field of patent law.

[0174] As used herein in the specification and claims, the phrase “at least one” relating to a list of one or more elements should be understood to mean at least one element selected from any one or more elements in the list, but not necessarily including at least one of each element specifically listed in the list, and does not exclude any combination of elements in the list. This definition also allows for the optional presence of elements other than those specifically identified within the list of elements referred to by the phrase “at least one,” whether related to or unrelated to those specifically identified elements. Thus, as a non-limiting example, “at least one of A and B” (or equivalently, “at least one of A or B”, or equivalently, “at least one of A and / or B”) can be understood to mean, in one embodiment, at least one, optionally including more than one A, while B is absent (and optionally including elements other than B); in another embodiment, at least one, optionally including more than one B, while A is absent (and optionally including elements other than A); in yet another embodiment, at least one, optionally including more than one A and at least one, optionally including more than one B (and optionally including other elements); and so on.

[0175] In the claims and the foregoing description, all transitional phrases, such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” etc., shall be understood as open-ended, meaning including but not limited to. Only the transitional phrases “consisting of” and “consisting substantially of” shall be closed or semi-closed transitional phrases, respectively, as described in Section 2111.03 of the U.S. Patent Examination Procedure Manual.
