Attorney Docket No.10485-023WO1 SELF-FORTIFYING HYDROPHOBIC POLYMER NETWORKS CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of priority to U.S. Provisional Application No. 63 / 698,318, filed September 24, 2024, which is incorporated by reference herein in its entirety. BACKGROUND
[0001] Polymers that can readily repel high surface tension liquids (such as water) are known as hydrophobic polymers. Due to extreme water repellency of hydrophobic polymers, they have found extensive utility in applications such as water-resistant fabrics, anti-fouling surfaces, self-cleaning coatings, corrosion protection, biomedical devices, liquids separation, packaging materials, non-stick cookware, and ice / frost protection. Among the chemistries that can enable hydrophobic wettability, the polymers with functional groups including methylene (-CH2-), methyl (-CH3), difluoromethylene (-CF2-), and trifluoromethyl (-CF3) are common. While they are effective in reducing solid surface energy and enhancing hydrophobic wettability, these polymers can pose environmental challenges due to their toxicity. In particular, the fluoropolymers consisting of (-CF2-) and (-CF3) functional groups such as per- and polyfluorinated Substances (PFAS) can cause severe health and environmental issues. The production of other synthetic hydrophobic polymers, often derived from petrochemicals, also typically involves significant energy inputs, and requires chemicals with detrimental effects on the environment. Vegetable oil-derived (bio-based) hydrophobic polymers are attractive alternatives for synthetic counterparts as they present readily available and more sustainable resources. These polymers can offer performance similar to their synthetic counterparts while significantly reducing detrimental effects on the environment.
[0002] Similar to other hydrophobic polymers, vegetable oil-derived hydrophobic polymers can experience structural degradation and compromised properties when exposed to environment for sufficiently long time. The factors that can contribute to structural degradation of polymers include water sorption, varying and / or elevated temperatures, as well as physical wear and tear. In particular, extended exposure of these hydrophobic polymers to water either in liquid or vapor form can cause degradation through several mechanisms such as hydrolysis, swelling and plasticization, leading to compromised mechanical and thermal properties.
[0003] There remains a need for improved hydrophobic polymers with enhanced resistance to hydrolytic degradation. There remains a need for hydrophobic polymers that do not include PFAS and other harmful chemicals.Attorney Docket No.10485-023WO1 SUMMARY

[0034] As used herein, the designation of a polyvalent moiety without specifying the specific order of attachment is intended to cover all possible arrangements. By way of example, a compound represented by the formula: A-X-B, wherein X is NHC(=O) embraces both:
[0035] As used herein, a chemical bond depicted: represents either a single, double, ortriple bond, valency permitting. By way of example,
[0036] Some compounds disclosed herein may exist as one or more tautomers. Tautomers are interconvertible structural isomers that differ in the position of one or more protons or other labile atom. By way of example:.
[0037] Unless stated to the contrary, a substituent drawn without explicitly specifying the point of attachment indicates that the substituent may be attached at any possible atom. For example, in a benzofuran depicted:,Attorney Docket No.10485-023WO1 the substituent may be present at any one of the six possible carbon atoms.
[0038] As used herein, the term “null,” when referring to a possible identity of a chemical moiety, indicates that the group is absent, and the two adjacent groups are directly bonded to one another. By way of example, for a genus of compounds having the formula CH3-X-CH3, if X is null, then the resulting compound has the formula CH3-CH3. A group having the subscript ‘0’ is understood to represent a null group as well. By way of example, in the compound CH3-(X)z-CH3, if X is CH2and z is 0, then the compound has the formula CH3-CH3.
[0039] A bracketed functional group with a subscripted variable should be understood to denote the number of repeated bracketed groups present. For example, a number that is selected from 0 or 1 should be interpreted as follows:.
[0040] In certain instances, two or more variable groups may together form a ring. It is understood that any depicted atoms separated the identified groups will themselves form part of the ring:
[0041] When the variable groups are substituted on an aromatic system the new ring will be a fused ring, and unless specified to the contrary may be either aromatic or non-aromatic, carbocyclic or heterocyclic:
[0042] The ring may further be defined by the number of carbon atoms in the specific ring formed by the variable groups, which includes the atoms separating the variable groups:
[0043] Each of the above results when R1and R2together form a six membered (or six atom) ring. Other rings, including 3, 4, 5, 7, and 8-member rings may also be formed, and may be further limited by a specified number of carbon atoms. Although the singular “a ring” mayAttorney Docket No.10485-023WO1 be used to define the group, unless specified to the contrary both monocyclic and polycyclic rings are possible:
[0044] Unless stated to the contrary, a formula with chemical bonds shown only as solid lines and not as wedges or dashed lines contemplates each possible isomer, e.g., each enantiomer, diastereomer, and meso compound, and a mixture of isomers, such as a racemic or scalemic mixture. Unless stated to the contrary, a formula depicting one or more stereochemical features does not exclude the presence of other isomers.
[0045] Some compounds disclosed herein may exist as one or more tautomers. Tautomers are interconvertible structural isomers that differ in the position of one or more protons or other labile atom. By way of example:.
[0046] The prevalence of one tautomeric form over another will depend on the specific chemical compound as well as its local chemical environment. Unless specified to the contrary, the depiction of one tautomeric form is inclusive of all possible tautomeric forms. POLYMERS

[0091] The crosslinked network can include the epoxidized lipid and epoxy-alkoxysilane in a variety of weight ratios. In some implementations, the weight ratio of the epoxidized lipid:epoxy-alkoxysilane in the crosslinked network can be 1:1 or more (e.g., 2:1 or more, 3:1 or more, 3.95:1 or more, 4:1 or more, 5:1 or more, 6:1 or more, 7:1 or more, 8:1 or more, 8.9:1 or more, 9:1 or more, 10:1 or more, 11:1 or more, 12:1 or more, 13:1 or more, 14:1 or more, 15:1 or more, 16:1 or more, 17:1 or more, 18:1 or more, or 19:1 or more).

When the crosslinked network comprises a plurality of lipids or alkoxysilanes, the weight ratios refer to the total of each component.
[0093] Without being bound by any theory, the self-fortifying nature of the networks in the hydrophobic polymer is believed to be due to the hydrolysis and crosslinking of siloxane groups following exposure to water. The crosslinked networks are useful as coatings, especially in coatings expected to be exposed to water, whether due to climate or use conditions. The networks are less susceptible to degradation from exposure to water than conventional polymer and polymer networks. In some implementations, the networks can be used in paints, sealants, protective coatings, and liquid separation membranes.Attorney Docket No.10485-023WO1
[0094] The disclosed polymers are useful in a wide variety of contexts, and may be deployed wherever hydrophobic polymers are used. The polymers can be used in textiles and apparel, electronics, transportation and automotive, construction and building materials, medical devices , agriculture and environmental, consumer products, and optical / imaging.

EXAMPLES
[0095] The following examples are for the purpose of illustration of the invention only and are not intended to limit the scope of the present invention in any manner whatsoever. Example 1
[0096] A solution was prepared in a vial by dissolving 100 mg of benzyl(4-hydroxyphenyl) methylsulfonium hexafluoroantimonate (“BHMH”) in 1000 mg of 3-glycidoxypropyl- trimethoxysilane (“GPTMS”). Subsequently, epoxidized soybean oil (“ESO”) (8900 mg) was added, and the vial was stirred for 30 minutes to obtain a transparent solution. For comparison, a solution of only ESO (i.e., without GPTMS) was also prepared by dissolving 100 mg of BHMH in ^50 mg ethanol followed by adding 9900 mg of ESO.
[0097] The solutions were poured in cylindrical silicone molds (diameter ^ 0.5 inch, height ^ 0.5 inch). The molds were placed on a hot plate heated to 110°C to perform thermal polymerization. Example 2
[0098] Materials and polymer solutions:
[0099] Materials: The vegetable oil-derived self-fortifying hydrophobic polymer was synthesized using epoxidized soybean oil (ESO) as the main monomer and 3-glycidoxypropyl- trimethoxysilane (GPTMS) as the organosilane monomer. ESO is derived from soybean oil through the epoxidation process [1]. As a replacement for conventional petroleum-based resins, this vegetable oil-derived material has been utilized in preparation of low-cost green bio-basedAttorney Docket No.10485-023WO1 epoxy polymers [2]. The monomer of ESO contains a long hydrocarbon chain consisting of low-solid surface energy Methylene (-CH2-) and Methyl (-CH3) groups, which can introduce hydrophobic wettability. ESO can be readily converted to a high-strength solid epoxy polymer through a ring-opening polymerization reaction [3].
[0100] GPTMS is an organosilane monomer that contains three hydrolyzable alkoxy functional groups (i.e., trialkoxysilyl group) and an epoxy functional organic chain. It can be utilized as an organic binder to increase the strength of a material [4].
[0101] In addition to the monomers, a thermally-latent cationic catalyst / initiator, benzyl(4- hydroxyphenyl) methylsulfonium hexafluoroantimonate (BHMH) was utilized for the synthesis of the polymer [5]. These catalysts / initiators can offer several advantages such as inertness under normal conditions and the ability to release active species only upon stimulation at specific temperatures, which enhances the storage stability of the system[6, 7]. Further, the polymers cured by these catalysts / initiators present lower shrinkage and superior mechanical properties [8]. The chemical structures of the materials are shown in FIG.1.
[0102] Polymer solutions: Polymer solutions with the following compositions of ESO, GPTMS, and BHMH were prepared (TABLE 1): TABLE 1. Composition of polymer solutions.
[0103] First, a polymer solution was prepared in a vial by dissolving BHMH in GPTMS. Subsequently, ESO was added, and the vial was stirred for 30 minutes to obtain a transparent solution. The polymer samples were prepared by thermally curing (polymerization) the polymer solutions on a hotplate at ^110°C. The polymer samples were utilized for a variety of characterization tests as described below.
[0104] Characterization tests:
[0105] Liquid wettability testing: Prior to investigating the liquid wettability, the polymers were coated onto glass substrates. Approximately 500 µL of each polymer solution was cast on glass substrates (size = 7.5 cm × 2.5 cm), followed by heating on a hotplate to completeAttorney Docket No.10485-023WO1 polymerization and obtain solid polymer coatings. The liquid wettability of the polymer coatings was investigated by measuring the dynamic (i.e., advancing and receding) contact angles of water (surface tension, ^lv ^ 72.7 mN / m), formamide (^lv ^ 58.2 mN / m), rapeseed oil (^lv ^ 35.7 mN / m), and n-hexadecane (^lv ^ 27.4 mN / m) at room temperature utilizing a goniometer (Model: Rame hart 210). The maximum advancing and receding contact angles of different liquids obtained on polymers prepared with various compositions are provided in TABLE 2. TABLE 2. Advancing and receding contact angles of different liquids on the polymers.
[0106] The representative goniometric photos obtained during the measurement of advancing and receding contact angles for different liquids are shown in FIG.2.
[0107] All polymer formulations show advancing contact angles for water greater than 90° confirming their hydrophobic wettability. In addition, formamide as another high surface tension liquid is effectively repelled, with advancing contact angles exceeding 76° across all polymer formulations. These results indicate no significant differences in liquid repellency among the tested formulations.
[0108] Shore A hardness testing: The effect of self-fortifying property of the polymer on its mechanical properties was investigated by performing Shore A hardness tests utilizing a DeFelsko PosiTector SHD hardness tester. The Shore A hardness value is expressed as a dimensionless number ranging from 0 to 100. Shore A hardness tests were performed on polymers that had been submerged in 50:50 wt% water:ethanol mixture for 0, 5, 10, and 15 days, and then dried in a dehydrator at 80°F (26.6°C) for 1 day. The measured Shore A hardness values for the polymers are summarized in TABLE 3.Attorney Docket No.10485-023WO1 TABLE 3. Shore A hardness measurements of the polymers.
[0109] These results indicate that the S3 polymer exhibited the greatest increase in Shore A hardness, rising from 79.96^±^0.50 to 89.4^±^0.70 after 10 days of submersion in a water:ethanol mixture. The increase in hardness can be attributed to the hydrolysis reaction at the trialkoxysilyl (-Si-O-CH3) functional groups of GPTMS, leading to formation of silanol groups (-Si-OH). The presence of water in the water:ethanol mixture can initiate this hydrolysis reaction. Subsequently, the condensation reactions between silanol groups caused formation of new silicone-oxygen covalent bonds (Si-O-Si) as additional crosslinks, which can improve the strength of the polymer [9, 10] (FIG.3).
[0110] Note that Shore A hardness could not be measured for the S4 polymer after 10 and 15 days of submersion, as the samples were too brittle and fractured during the hardness testing.
[0111] Tensile testing: The tensile testing samples were prepared by casting the polymer solutions into non-stick rectangular silicone molds (Length= 135 mm, Width= 14 mm, Thickness^ 2 mm). Tensile tests were performed following the ASTM D3039 standard. A benchtop testing equipment (Model: Mark-10 F505) was used and the polymer samples were clamped at both ends using two grips. Testing was performed at a constant strain rate of 2 mm / min during which the load-displacement data were collected. The tensile stress was determined by dividing the measured load by the cross-sectional area of the polymer sample. The representative photo of the tensile test sample is presented in FIG. 4. The plots of tensile stress vs. displacement for different polymer formulations submerged in 50:50 wt% water:ethanol mixture for 0, 5, 10, and 15 days are demonstrated in FIG.5. The ultimate tensile strength (highest tensile stress) values obtained from tensile tests are summarized in TABLE 4.Attorney Docket No.10485-023WO1 TABLE 4. Ultimate tensile strength measurements of the polymers.
[0112] The results of tensile tests show a decrease in ultimate tensile strength values with the increase in the time of submersion in water:ethanol mixture. This reduction may be related to the increased brittleness of the polymers as indicated by the rising hardness values (see TABLE 3), which limits the polymers’ ability to elongate under tensile loading and therefore reduces their tensile strength values.
[0113] The ultimate tensile strength decreased from 0.746 MPa to 0.637 MPa for polymer S1, marking a 0.109 MPa decrease, whereas for polymer S4, it decreased significantly from 1.336 MPa to 0.485 MPa, marking a decrease of 0.851 MPa. This difference can be attributed to a lower concentration of GPTMS in S1 compared to S4. A lower concentration of GPTMS in S1 caused a less pronounced self-fortifying effect resulting in limited increase in hardness and brittleness. In contrast, the higher concentration of GPTMS in S4 caused a significant self- fortifying effect resulting in an excessive increase in hardness and brittleness, which in turn limited the elongation ability and ultimate tensile strength of the polymer.
[0114] Compression testing: The compression testing samples were prepared by casting the polymer solutions into non-stick cylindrical plastic molds (Height^ 10 mm, Diameter= 17.6 mm). Compression tests were conducted using the benchtop testing equipment (Model: Mark- 10 F505). Testing was performed at a constant strain rate of 2 mm / min during which the load- displacement data were collected. The compression stress was determined by dividing the measured load by the cross-sectional area of the cylindrical polymer sample. The representative photo of the compression test sample is presented in FIG. 6. The plots of compression stress vs. displacement for different polymer formulations submerged in 50:50 wt% water:ethanol mixture for 0, 5, 10, and 15 days are demonstrated in FIG.7. The ultimate compression strength (highest compression stress) values obtained from compression tests are summarized in TABLE 5.Attorney Docket No.10485-023WO1 TABLE 5. Ultimate compression strength measurements of the polymers.
[0115] The results of compression tests show that the ultimate compression strength values increased with polymers (S1, S2, and S3) submersion in the water:ethanol mixture. This improvement can be attributed to the increased hardness values (see TABLE 3), which indicate enhanced stiffness and resistance to deformation. These characteristics are particularly beneficial under compressive loading, where the polymers can benefit from a denser network structure. The self-fortifying effect driven by the formation of additional crosslinks resulted in a denser polymer network that could withstand compressive forces more effectively.
[0116] Note that the value of ultimate compression strength generally decreased for the S4 polymer after submersion in the water:ethanol mixture. This reduction is attributed to the high concentration of GPTMS in S4 that caused excessive self-fortifying effect. The resulting brittleness compromised the polymer’s ability to withstand compressive forces.
[0117] Corrosion testing: Corrosion tests were performed using the potentiodynamic polarization method with a three-electrode setup. In this configuration, thin mild steel sheets (Length= 100 mm, Width= 14 mm, Thickness^ 0.65 mm) coated with S1-S4 polymers were utilized as the working electrodes while platinum and Ag / AgCl were used as the counter and reference electrodes, respectively. Saline water (3.5 wt% NaCl in water) was utilized as the corrosive medium (electrolyte). The measurements were performed using a Gamry 1010T potentiostat, and the Tafel plots were recorded at a scan rate of 10 mV / s.
[0118] FIGS. 8A-8B show photos of the thin mild steel sheet before and after coating, respectively. Note that the thickness of the coatings was approximately 0.60 mm.
[0119] FIG.9 shows the Tafel plots obtained from the potentiodynamic polarization tests. The extrapolation method was used to determine the corrosion potential (Ecorr) and corrosion current density (Icorr). The Ecorr and Icorr values obtained for polymers S1-S4 areAttorney Docket No.10485-023WO1 summarized in TABLE 6. Note that a more positive value of Ecorr typically indicates lower corrosion probability, while Icorr is a measure of corrosion rate [11, 12]. TABLE 6. Summary of Ecorrand Icorrvalues for the polymers.
[0120] The results indicate that polymer S2, with the lowest corrosion current density of 0.522 nA / cm2 provides the highest level of corrosion protection in saline water.
[0121] Distinct features of polymers: While self-strengthening polymers have been reported in prior studies [9, 10, 13-17], in these works, the self-strengthening mechanism was also attributed to the hydrolysis and condensation of the alkoxysilyl (-Si-O-CH3) functional groups, resulting in formation of additional crosslinks, which enables progressive improvement in mechanical properties of polymers. However, the current work differs from those prior studies in several aspects as summarized below.
[0122] Unlike conventional polymers, completely different monomers were used in the present work, which include Epoxidized soybean oil (ESO) and 3-glycidoxypropyl- trimethoxysilane (GPTMS). Furthermore, the organosilane monomer used in the present work is 3-glycidoxypropyl-trimethoxysilane (GPTMS), which also contains alkoxysilyl moiety. Unlike conventional polymers, the head group in GPTMS consists only of an epoxide ring.
[0123] The hydrolysis and condensation of the alkoxysilyl functional groups that cause self-fortifying in the polymer developed in present work is also initiated by submersion in a liquid containing water (e.g., water-ethanol mixture). Additionally, the polymer developed in this work partially undergoes self-fortification during the thermal polymerization process when exposed to heat.
[0124] Unlike conventional polymers, the catalyst / initiator used in the present work is a thermally-latent cationic initiator (heat-responsive catalyst / initiator), benzyl(4-hydroxyphenyl) methylsulfonium hexafluoroantimonate (BHMH). This catalyst / initiator can undergo thermal decomposition to release protons that can initiate polymerization
[0018] .
