 1 is a flowchart illustrating a method of manufacturing a transparent thin film according to an embodiment of the present invention.

Referring to FIG. 1, a method (S100) for manufacturing a transparent thin film according to an embodiment of the present invention includes a step S110 of forming a transparent thin film made of nanofibers, a step S120 coating a transparent thin film, (S130).

The nanofibers in step S110 of fabricating the transparent thin film made of nanofibers according to the present embodiment may be selected from the group consisting of nylon-6, polyacrylonitrile (PAN), polylactic acid (PLA), and cellulose acetate cellulose acetate: CA).

Further, in the step of coating the transparent thin film according to the present embodiment (S120), the transparent thin film may be coated with a coating material having a refractive index similar to that of the nanofiber.

Here, the coating agent according to this embodiment may include nylon-6, polyacrylonitrile (PAN), polylactic acid (PLA), and cellulose acetate (CA).

Therefore, according to this embodiment, the nanofiber composing the transparent thin film is coated with one of nylon-6, polyacrylonitrile (PAN), polylactic acid (PLA) and cellulose acetate (CA) And the pores between the nanofibers can be filled with one of nylon-6, polyacrylonitrile (PAN), polylactic acid (PLA) and cellulose acetate (CA) ) Reference).

Here, nanofibers prepared from one of nylon-6, polyacrylonitrile (PAN), polylactic acid (PLA) and cellulose acetate (CA) have a light transmittance of 90% or more. In addition, nylon-6, polyacrylonitrile (PAN), polylactic acid (PLA), and cellulose acetate (CA) coatings coated on the transparent thin film each have a light transmittance of 90% or more .

 Therefore, according to the present embodiment, the nanofiber composing the transparent thin film and the nylon-6, the polyacrylonitrile (PAN), the polylactic acid (PLA) and the cellulose acetate CA) may have similar refractive indices.

As a result, the transparent thin film including the nanofiber coated with the coating agent according to the present embodiment may have a light transmittance of 90% or more.

Therefore, according to this embodiment, a transparent thin film having excellent light transmittance can be provided by coating with a coating including a nanofiber and being flexible and having a refractive index similar to that of a nanofiber, thereby providing a transparent thin film.

2 is a flowchart illustrating a method of fabricating a flexible fiber transparent electrode including a polyaniline nanowire according to an embodiment of the present invention.

Referring to FIG. 2, a method S200 of fabricating a flexible fiber transparent electrode including a polyaniline nanowire according to an embodiment of the present invention includes the steps of fabricating a transparent thin film made of nanofibers (S210) (S220), and removing the transparent thin film from the mixed reaction solution (S230).

A method (S210) for fabricating a transparent thin film made of nanofibers according to this embodiment and a transparent thin film thus formed are the same as the above-described transparent thin film manufacturing method (S100) and the resulting transparent thin film. Is omitted.

In the step of immersing the thin film according to the present embodiment in the mixed reaction solution (S220), the mixed solution may include an aniline monomer, a polymerization initiator, and an acid solution.

Here, the molar concentration of the aniline monomer may be between 25 mM and 2000 mM, and the molar concentration of the polymerization initiator may be between 5 mM and 200 mM. At this time, the polymerization initiator may include an ammonium persulfate (APS) initiator.

In addition, the mixed reaction solution according to this embodiment may include an acid solution. Here, the acid solution may include hydrochloric acid (HCl), sulfuric acid (H 2 SO 4), and nitric acid (HNO 3 ) having a molar concentration of 0.1 M or more and 2.0 M or less.

At this time, if the molar concentration of the acid solution is less than 0.1M, the aniline monomer is not dispersed, so that the polyaniline nanowire is not formed on the surface of the electrode, and if the molar concentration of the acid solution is 2M or more, the electrode is decomposed.

In addition, the precipitation time of the thin film in the mixed reaction solution may be from 1 hour to 3 hours or less.

According to this embodiment, while the thin film is precipitated in the mixed reaction solution, the polyaniline polymerized by the polymerization initiator in the mixed reaction solution adheres to the surface of the thin film, and the polyaniline nanowire may be formed on the surface of the thin film .

However, if the precipitation time of the thin film in the mixed reaction solution is less than 1 hour, the polyaniline nanowire is not sufficiently formed on the surface of the electrode, so that the electric conductivity characteristic of the flexible fiber transparent electrode is lowered. In addition, when the precipitation time of the thin film in the mixed reaction solution exceeds 3 hours, the polyaniline nanowire is not formed on the surface of the electrode. In detail, when the aniline monomer is immersed in the mixed reaction solution and polymerized by the polymerization initiator for more than 3 hours, a lump of polyaniline polymer rather than polyaniline nanowire may be formed on the surface of the electrode. According to this embodiment, as the molar concentration of the aniline monomer increases, the density of the polyaniline nanowire formed on the surface of the electrode increases. On the contrary, as the molar concentration of the aniline monomer decreases, the density of the polyaniline nanowire formed on the surface of the electrode increases Lower.

Therefore, according to this embodiment, the higher the molar concentration of the aniline monomer dissolved in the mixed reaction solution, the lower the light transmittance of the transparent electrode, and the lower the light transmittance of the transparent electrode, the higher the surface resistance of the transparent electrode.

As a result, according to this embodiment, the molar concentration of the aniline monomer dissolved in the mixed reaction solution and the light transmittance of the transparent electrode are inversely related to each other, and the light transmittance of the transparent electrode and the surface resistance of the transparent electrode are proportional to each other.

For example, when the molar concentration of the aniline dissolved in the reaction solution is between 25 mM and 2000 mM, the light transmittance of the transparent electrode may be between 81.3% and 39.0%, and the light transmittance of the transparent electrode may be between 87.2% and 39.0% The surface resistance of the transparent electrode can be between 8700 ohms / sq and 188 ohms / sq.

Accordingly, according to the present embodiment, it is possible to provide a flexible fiber transparent electrode including a polyaniline nanowire whose light transmittance and surface resistance of the transparent electrode are controlled by controlling the molar concentration of the aniline monomer dissolved in the mixed reaction solution.

Here, the relationship between the molar concentration of the aniline monomer, the light transmittance of the transparent electrode, and the surface resistance of the transparent electrode will be described in more detail in the following Experimental Examples.

As shown in FIG. 6, the surface resistance of the transparent electrode measured after 1000 bending tests was analyzed to be about 10% higher than that of the initial state, and the structural change of the transparent electrode according to this embodiment It is not large even after 1000 bending tests.

Therefore, according to this embodiment, a flexible fiber transparent electrode including a polyaniline nanowire having high flexibility can be provided.

Here, the flexibility of the transparent electrode according to this embodiment will be described in more detail in the following experimental examples.

In addition, according to the present embodiment, after removing the thin film from the mixed reaction solution, the transparent thin film is washed with deionized water (S240), the transparent thin film is dipped in the post-treatment solution (S250) And removing (S260) a step from the post-treatment solution.

Here, the post-treatment solution may include an acid solution, and the acid solution may include hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3) having a molar concentration of 0.1M or more to 2.0M or less. In this case, if the molar concentration of the acid solution is less than 0.1M, the aniline monomer is not dispersed, so that the polyaniline nanowire is not formed on the surface of the electrode. If the molar concentration of the acid solution is 2M or more, . In addition, as shown in FIG. 9, the capacitance retention of the transparent electrode according to the present embodiment measured after 1000 charge / discharge tests can be maintained at about 61%.

Therefore, according to this embodiment, a flexible fiber transparent electrode including a polyaniline nanowire having a stable capacitance retention can be provided.

Here, the electrostatic capacity of the transparent electrode according to this embodiment will be described in more detail in the following experimental examples.
