[0041] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings, so that those skilled in the art to which the present disclosure pertains can easily implement the present disclosure.

[0042] Figure 1 is a diagram schematically illustrating a configuration of a composition 100 according to one exemplary embodiment, and Figure 2 is a diagram schematically illustrating a configuration of a composition 100 according to one exemplary embodiment.

[0043] The composition according to one exemplary embodiment can exert a bactericidal and / or virucidal function. The term "composition" can be replaced by terms such as complex or mixture, and there is no particular limitation on bacteria or viruses that are the target of the bactericidal and / or virucidal function of the composition 100.

[0044] The composition 100 can include at least one organic dye 110 and at least one ionic liquid 120. Figure 1 The X anion and the Y cation in the formula (1) respectively show an anion and a cation constituting the organic dye 110 or an anion and a cation in the organic dye 110, and Figure 1 The AB2 cation and the C anion in the formula (2) respectively show a cation and an anion constituting the ionic liquid 120 or a cation and an anion in the ionic liquid 120. Figure 2 It is exemplified that the composition 100 according to one exemplary embodiment can include rose bengal as the organic dye 110 and trishexadecylphosphonium chloride as the ionic liquid 120, to illustrate the configuration of an exemplary composition.

[0045] The organic dye 110 according to one exemplary embodiment can refer to an organic dye 110 capable of reacting with visible light and exerting a bactericidal and / or virucidal function. The organic dye 110 can react with visible light and generate at least singlet oxygen (e.g. 1 O2). For example, the organic dye 110 can receive visible light and absorb energy, and thus, the triplet energy of the dye can be transferred to surrounding oxygen molecules and generate singlet oxygen. In addition, because the generated singlet oxygen has strong oxidizing power, it can exert a bactericidal and / or virucidal function.

[0046] On the other hand, the organic dye 110 can be decolorized when singlet oxygen (e.g., dioxygen, dioxidene, O2, and / or O=O) reacts with bacteria or viruses. The organic dye 110 can be decolorized while it exerts a bactericidal and / or virucidal function, and lose its original color, and in this way, it can indicate that a bactericidal and / or virucidal function is exerted.

[0047] For example, the organic dye 110 can include at least one of methylene blue, rose bengal, and phthalocyanine, krysene, or yeosin. That is, the organic dye 110 according to one exemplary embodiment can be selected as one of various organic dyes 110 in the aforementioned examples, and it can also be composed of a combination of two or more organic dyes 110 in the aforementioned examples. Other elements can also be present in the organic dye 110.

[0048] The ionic liquid 120 according to one exemplary embodiment can include an ion exhibiting hydrophobicity, and can have a charge opposite to a charge included in the organic dye 110 in an ionized state. That is, the ionic liquid 120 according to one exemplary embodiment is characterized by having hydrophobicity, and / or secondarily by having a charge opposite to a charge included in the organic dye 110 in an ionized state. Each of the two characteristics will be described in detail below. Other elements can also be present in the ionic liquid 120.

[0049] First, one of the ions included in the ionic liquid 120 according to one exemplary embodiment can have hydrophobicity (which will hereinafter be simply referred to as a 'hydrophobic ion'). Here, it is preferable that the hydrophobicity be sufficient to cause the entire composition 100 including the organic dye 110 and the ionic liquid 120 to exhibit hydrophobicity. The hydrophobic ion can include a functional group capable of counteracting polarity of a central atom of the ion. For example, non-polar functional groups such as alkane and ether, etc. can be described as functional groups capable of contributing to the hydrophobicity of the composition 100.

[0050] For example, the hydrophobic ion can include a central atom having a charge opposite to a charge included in the organic dye 110 in an ionized state, and at least one alkyl group. Here, the central atom can be at least one of nitrogen, phosphate, boron, oxygen, or sulfur, and the at least one alkyl group can include at least three carbon atoms. For example, the hydrophobic ion can include four or more alkyl groups, and the at least one alkyl group can include at least six carbon atoms.

[0051] In one exemplary embodiment, it can be preferable that the hydrophobic ion not include a functional group exhibiting hydrophilicity. Here, the functional group exhibiting hydrophilicity refers to, for example, polar functional groups such as amide, carbonyl, alcohol, etc.

[0052] In the above, the condition under which the ion included in the ionic liquid 120 according to one exemplary embodiment becomes hydrophobic is described in detail, but the condition under which the ion included in the ionic liquid 120 becomes hydrophobic can differ depending on the kind of the organic dye 110 and the ionic liquid 120.

[0053] Second, the hydrophobic ion included in the ionic liquid 120 can have a charge opposite to a charge included in the organic dye 110 in an ionized state. That is, as shown in Figure 1 and Figure 2 The hydrophobic ion can be selected to be an ion having a charge opposite to a charge included in the organic dye 110 in an ionized state, so that electrostatic attraction can occur between the ionic liquid 120 and the organic dye 110.

[0054] For example, if at least one of the atoms included in the central atoms of the organic dye 110 has a positive charge when the organic dye 110 is in an ionized state, the ionic liquid 120 can include ions that exhibit hydrophobicity and have a negative charge. Conversely, if at least one of the atoms included in the central atoms of the organic dye 110 has a negative charge when the organic dye 110 is in an ionized state, the ionic liquid 120 can include ions that exhibit hydrophobicity and have a positive charge. On the other hand, if at least one of the atoms included in the central atoms of the organic dye 110 carries both a positive charge and a negative charge when the organic dye 110 is in an ionized state, the ionic liquid 120 can exhibit hydrophobicity and have a negative charge or a positive charge.

[0055] For example, if the organic dye 110 carries a positive charge in an ionized state, such as rose Bengal or phthalocyanine, the hydrophobic ions included in the ionic liquid 120 can include at least one of phosphonium, ammonium, imidazolium, or pyrrolidinium.

[0056] As another example, if the organic dye 110 carries a negative charge in an ionized state, such as methylene blue, the hydrophobic ions included in the ionic liquid 120 can include at least one of tetrafluoroborate, bis(trifluoromethylsulfonyl)imide, or hexafluorophosphate.

[0057] In one exemplary embodiment, if the ionic liquid 120 includes hydrophobic ions having a charge opposite to the charge included in the organic dye 110 in an ionized state, the ionic liquid 120 according to one exemplary embodiment can be composed of a combination of two or more ionic liquids 120 according to the examples as described above.

[0058] As described in the above various embodiments, the composition 100 according to one exemplary embodiment exerts a bactericidal and / or viricidal function, and is not easily washed off by moisture or the like, so the composition 100 can solve the problem of contamination of the target product by the organic dye 110 or damage to the user while maintaining the bactericidal and / or viricidal function.

[0059] In addition, when the composition 100 according to one exemplary embodiment exerts a bactericidal and / or viricidal function, the life of the bactericidal and / or viricidal function can be intuitively indicated by a color change of the surface of the target product to which the composition 100 is applied, so that the reliability of the technology can be significantly improved by visually seeing that the bactericidal and / or viricidal function is actually working.

[0060] Figure 3 is a drawing showing an exemplary method of preparing the composition 100 in the form of a solution according to one exemplary embodiment.

[0061] The composition 100 according to one exemplary embodiment can be prepared in a solution form by a simple combination of the organic dye 110 and the ionic liquid 120.

[0062] In the preparation of the solution, an auxiliary solvent for facilitating ionization of the organic dye 110 and adjusting the viscosity of the solution can be used. Specifically, the composition 100 according to one exemplary embodiment can further include at least one auxiliary solvent selected from water and ethanol. Here, the mass of the auxiliary solvent can be 0 to 500 times the mass of the organic dye 110.

[0063] On the other hand, it is preferable to determine the molar ratio of the organic dye 110 and the ionic liquid 120 included in the composition 100 in consideration of the fact that if the ratio of the organic dye 110 is too low, the sterilization and / or virucidal effect can be reduced, and on the other hand, if the ratio of the organic dye 110 is too high, the organic dye 110 can be eluted into the target substance.

[0064] For example, the number of moles of the organic dye 110 included in the composition 100 can be 1 times to less than 10 times the number of moles of the ionic liquid 120. More specifically, the number of moles of the organic dye 110 can be 2 times to less than 5 times the number of moles of the ionic liquid 120.

[0065] As shown in FIG. 1, Figure 3 If a solution in which the organic dye 110 is dissolved in an auxiliary solvent is mixed with the ionic liquid 120 and stirred, the composition 100 thus prepared can exist as a solution at room temperature. In addition, if the composition 100 according to one exemplary embodiment is prepared as a solution, the prepared solution is formed on the surface of a target object, and thus can exert a sterilization and / or virucidal function. That is, if the composition 100 according to one exemplary embodiment is prepared as a solution, the composition 100 can be easily used to be directly coated on a desired material.

[0066] For example, the composition 100 according to one exemplary embodiment can be coated on the surface of an object (such as a cell phone case, a television, a remote controller of a home appliance, an escalator handrail, an elevator button, etc.) that is frequently in contact with human skin. In addition to the above, the composition 100 can be implemented in the form of an adhesive film that can be adhered to and removed from an air purifier filter, a dust collector filter, and a desired surface. In addition to the above, there is no particular limitation to the type of product to which the composition 100 according to one exemplary embodiment can be applied.

[0067] Figure 4 is a view showing a method of preparing the composition 100 according to one exemplary embodiment in the form of a nanofiber.

[0068] In combining the organic dye 110 and the ionic liquid 120 with the polymer liquid, the composition 100 according to one exemplary embodiment can be prepared in the form of a nanofiber. That is, the composition 100 according to one exemplary embodiment can further include the polymer material 130 as well as the organic dye 110 and the ionic liquid 120, and the composition 100 can be formed in the form of a fiber in which the organic dye 110, the ionic liquid 120, and the polymer material 130 are combined.

[0069] For example, the polymer material 130 can include at least one of cellulose acetate or polyacrylonitrile. However, the present disclosure is obviously not limited thereto.

[0070] As shown in FIG. 1, the composition 100 according to one exemplary embodiment can be prepared in the form of a nanofiber in which the organic dye 110, the ionic liquid 120, and the polymer material 130 are combined. Figure 4 As shown in FIG. 1, the composition 100 according to one exemplary embodiment can be prepared in the form of a nanofiber in which the organic dye 110, the ionic liquid 120, and the polymer material 130 are combined.

[0071] Electrospinning is a method of applying an electric field between an electrode and a polymer solution and preparing a fiber as the solution flows from the electrode. Here, a pulling force is applied between the electrode and the solution, and the solution is broken and a fiber is generated, the diameter of which can be determined by the distance between the electrode and the solution, the flow rate of the solution, the surface tension of the solution, etc.

[0072] On the other hand, it is preferable to determine the mass of the organic dye 110 in consideration of the fact that if the ratio of the organic dye 110 is too low, the sterilization and / or virucidal effect can be reduced, and on the other hand, if the ratio of the organic dye 110 is too high, there can be a residual organic dye 110 that is not bonded to the polymer fiber.

[0073] For example, the mass of the organic dye 110 can be 0.1 to 20% by weight of the mass of the polymer material 130. More specifically, the mass of the organic dye 110 can be 1.0 to 3.0% by weight of the mass of the polymer material 130.

[0074] As described above, if the composition 100 according to one exemplary embodiment is prepared as a nanofiber, the organic dye 110 and the ionic liquid 120 can be uniformly formed on the polymer material 130, and thus, the composition 100 can be easily processed as an internal fiber of an air purifier, a disposable mask, a smart mask, etc. On the other hand, it is obvious that the composition 100 according to one exemplary embodiment can be prepared in various forms such as a sheet form and a film form, etc. as well as a fiber form including a nanofiber, according to the type of the target product.

[0075] Figure 5This is a diagram illustrating an experimental example of the inactivation effect of composition 100 according to an exemplary embodiment on a virus.

[0076] exist Figure 5 In the experimental example, rose red (hereinafter referred to as RB) was used as the organic dye 110, and trihexyltetradecylphosphonium chloride (hereinafter referred to as IL, an abbreviation for ionic liquid) was used as the ionic liquid 120. Additionally, polyacrylonitrile (hereinafter referred to as PAN) was used as the polymer material 130, and N,N-dimethylformamide (hereinafter referred to as DMF) was used as the auxiliary solvent.

[0077] like Figure 5 As described in Table 530, according to Figure 5 The composition 100 of the experimental example contains the following components by mass: PAN 1.0 g, DMF 9.0 g, RB 0 ~ 0.065 g, and IL 0 ~ 0.0335 g. Furthermore, the ratio of RB to IL is selected relative to the polymer material 130. Additionally, RB and IL are combined in a 1:1 molar ratio.

[0078] like Figure 5 As described in box 520, the virus used is φ×174, and the virus concentration is 2.0×10⁻⁶. 8 PFU / mL, area 2.0 × 2.0 cm 2 The buffer solution was 1 mM phosphate-buffered saline (PBS). Additionally, an Xe lamp with a visible light filter was used as the light source, with an LED distance of 2 cm and an illumination time of 30 min.

[0079] After preparing nanofibers according to an exemplary embodiment under the above experimental conditions, a virus inactivation experiment was performed by irradiating the prepared nanofibers with visible light. Figure 5 As shown in Figure 510, the nanofibers prepared according to an exemplary embodiment exhibit significantly improved virus-killing activity under visible light illumination compared to dark conditions, and in particular, the nanofibers exhibit even higher virus-killing activity, i.e., antiviral performance, when the amount of RB compared to the polymer material 130 is increased. The same effect is observed against bacteria.

[0080] Figure 6 This is a diagram illustrating an experimental example used to confirm the generation of singlet oxygen by composition 100 according to an exemplary embodiment.

[0081] exist Figure 6 In the experimental examples, according to the same Figure 5The ratio of the same materials and components in ( Figure 6 Nanofibers were prepared using 630 (of which), and the amount of singlet oxygen generated for each RB amount was determined by confirming the extent of decomposition of furfuryl alcohol (hereinafter referred to as FFA) that selectively reacts with singlet oxygen.

[0082] like Figure 6 As described in frame 620, the area is 2.0 × 2.0 cm. 2 1 mM PBS was used as the buffer solution. Additionally, a blue LED with a maximum wavelength of 470 nm was used as the light source, with an LED distance of 2 cm and an irradiation time of 60 min.

[0083] like Figure 6 As shown in Figure 610, in nanofibers prepared according to an exemplary embodiment, more than twice the amount of singlet oxygen is generated when IL is combined with RB compared to the case where RB is used alone. Furthermore, even greater amounts of singlet oxygen are generated when the ratio of IL combined with RB is increased by 2%, 5%, and 10%.

[0084] Figure 7 and Figure 8 This is a diagram illustrating an experimental example demonstrating the effect of composition 100 according to an exemplary embodiment not being washed into water.

[0085] Figure 7 The first box 710 in the diagram shows the state of nanofibers prepared by combining RB and IL according to an exemplary embodiment, immersed in water, and the state of nanofibers prepared by using RB without combining IL, immersed in water.

[0086] like Figure 7 As shown in the second box 720, when in Figure 7 When the nanofibers were removed after 30 minutes in the state of the first box 710, the organic dye 110 was not eluted into the water containing the nanofibers prepared by combining RB and IL, but in contrast, the organic dye 110 was eluted into the water containing the nanofibers prepared by using RB without combining IL.

[0087] On the other hand, such as Figure 8 As shown in Figure 810, when the mass ratio of RB to polymer material 130 is increased by 2%, 5%, 10%, and 20%, respectively, samples with a width and height of 2 cm are prepared, according to... Figure 7 Experiments were conducted, and the results showed that even when the amount of RB was increased to 20%, the organic dye 110 was not washed into the water.

[0088] Figure 9This is a diagram illustrating an experimental example of color change when composition 100 according to an exemplary embodiment exerts a virus inactivation effect.

[0089] exist Figure 9 In the experimental examples, the use of and Figure 5 In the experimental examples, the same materials were used as organic dye 110 and ionic liquid 120, and cellulose acetate (hereinafter referred to as CA) was used instead of PAN as polymer material 130, and water was used as auxiliary solvent. However, even when ethanol, DMF, etc. were used instead of water as auxiliary solvent, the experimental results did not produce substantial differences.

[0090] like Figure 9 As described in Table 930, the masses of each component are: CA 1.0 g, DMF 9.0 g, RB 0.013 g, IL 0.0067 g. Figure 9 In the experiments, the ratio of RB to IL was selected relative to polymer material 130. On the other hand, when RB and IL were combined, they were combined in a 1:1 molar ratio, and the amounts of RB and IL relative to polymer material 130 were selected as 2%.

[0091] like Figure 9 As described in box 920, the virus used has a diameter of φ×174 and a concentration of 2.0×10⁻⁶. 9 PFU / mL, area 2.0 × 2.0 cm 2 Furthermore, 10 mM PBS was used as the buffer solution. Additionally, the LED distance and irradiation time were 2 cm and 30 min, respectively.

[0092] Each implementation scheme described herein can be used in combination with any one or more other implementation schemes described herein.

[0093] After preparing nanofibers according to an exemplary embodiment under the above experimental conditions, a virus inactivation experiment was performed by irradiating the prepared nanofibers with visible light. Figure 9 As shown in Figures and Graphs 910, the nanofibers according to an exemplary embodiment are completely decolorized after six hours, and unlike before decolorization, the virus inactivation performance under visible light is significantly lower after decolorization.

[0094] Figure 10 This is a figure illustrating experimental examples used to confirm that no performance change occurs under visible light conditions when the composition 100 according to an exemplary embodiment does not contain organic dye 110.

[0095] exist Figure 10 In the experimental examples, the use of andFigure 9 the same materials as in the experimental example of Figure 9 but different from the experimental example of

[0096] As described in Table 1030 of Figure 10 the mass of each component was: CA 1.0 g, DMF 9.0 g, IL 0.0067 g. In addition, the ratio of the solution in which the RB and IL were combined was selected in comparison to the polymer material 130. In addition, when the RB and IL were combined, they were combined in a 1:1 molar ratio, and the amount of RB and IL in comparison to the polymer material 130 was selected to be 2%.

[0097] On the other hand, as described in block 1020 of Figure 10 the virus and light conditions used were the same as in the experimental example of Figure 9

[0098] As shown in the graph 1010 of Figure 10 there was no change in the virus inactivation performance under visible light conditions without the organic dye 110 included in the composition 100, and thus it can be confirmed that photosynthesis does not occur without the organic dye 110 included in the composition 100.

[0099] As described in each of the above embodiments, the composition 100 according to one exemplary embodiment exerts a bactericidal and / or virucidal function, and is not easily eluted by moisture or the like, and thus the composition 100 can solve the problem of the target product being contaminated with the organic dye 110 or the user being harmed while maintaining the bactericidal and / or virucidal function. In some exemplary embodiments, the composition can include, consist of, or consist essentially of, the recited / described elements.

[0100] In addition, although preferred embodiments have been shown and described, the present disclosure is not limited to the foregoing specific embodiments, and it is obvious that a person of ordinary skill in the art to which the present disclosure pertains can make various changes without departing from the spirit and scope of the present disclosure claimed by the appended claims. In addition, such changes should not be interpreted as departing from the technical concept or prospect of the present disclosure. Although the present disclosure has been explained and described with reference to various embodiments, it will be understood that the various embodiments are intended to be illustrative, rather than restrictive.
