Hereinafter, experimental examples according to the present invention will be specifically shown, and the present invention is not limited by the following experimental examples.
<Experimental Example 1>
Ag nanowires were dispersed in ethanol to form Ag nanowire dispersions. The Ag nanowires were contained in the Ag nanowire dispersion in an amount of 2 wt%, and the Ag nanowires having an average diameter of 27 nm and an average length of about 22 μm were used.
In order to prepare a transparent conductive coating film for preventing fogging, the Ag nanowire dispersion was coated on a transparent glass using a bar coating method with a conductive coating solution. At this time, the bar indicates the No. 3, and a moving speed of 3 mm / s.
When the visible light transmittance of the coated glass was about 75.6%, the sheet resistance of the coating film was 14.26? / ?. However, since the transparent conductive coating film formed by coating the Ag nanowire dispersion has weak adhesion, there is a problem that when the coating film is rubbed by hand, it is peeled off.
<Experimental Example 2>
Ag nanowire dispersion was prepared. The Ag nanowire dispersion was formed by dispersing Ag nanowires in ethanol. The Ag nanowires were contained in the Ag nanowire dispersion in an amount of 2 wt%, and the Ag nanowires having an average diameter of 27 nm and an average length of about 22 μm were used.
In order to prepare a transparent conductive coating film for preventing fogging which has high durability, a binder capable of improving the adhesion of the coating film is required. To synthesize these binders, glycidoxypropyl trimethoxysilane (GPTMS), vinyltrimethoxysilane (VTMS), tetraethyl orthosilicate (TEOS), ethanol ; EtOH), hydrochloric acid (HCl, hydrochloric acid) and distilled water (H 2 O, Distilled water) were used.
A synthesis solution was prepared by mixing GPTMS: VTMS: TEOS: EtOH: H 2 O at a volume ratio of 15: 15: 70: 20: 10, and a hydrochloric acid (HCl) solution was added as a catalyst to control the reaction rate of the precursors A hybrid binder was synthesized. The hydrochloric acid (HCl) solution was diluted to about 1000 times with 35% HCl in distilled water, and then 1.0wt% was added to the content of the synthesis solution. For the stability of the reaction, the hydrochloric acid solution was added at a temperature of about 4 캜, mixed at a temperature of about 60 캜 for about 4 hours, and then mixed at a room temperature for 24 hours at room temperature. The hybrid binder was prepared by adding a hydrochloric acid solution to the synthesis solution. And aged for synthesis.
Ethanol was added to the synthesized hybrid binder and diluted to form a hybrid binder solution. At this time, 5,000 parts by weight of the ethanol was added to 100 parts by weight of the hybrid binder.
The Ag nanowire dispersion and the hybrid binder solution were mixed at a weight ratio of 1: 5 and stirred to form a transparent conductive coating composition for preventing fading.
The transparent conductive coating composition for preventing fogging was coated on a transparent glass at a coating speed of 35 to 50 mm / s using a No. 10 bar by a bar coating method, dried at room temperature, Heat treatment was performed for 1 hour.
Table 1 below shows the characteristics of the transparent conductive coating film for preventing fogging according to the coating speed.
Bar coating generally has a higher transmittance because the thickness of the coating film becomes thinner as the coating speed increases. As shown in Table 1 above, when the coating speed is increased from 35 mm / s to 50 mm / s, the visible light transmittance is increased from 65% to 81%.
As the coating speed increased from 35 mm / s to 50 mm / s, the infrared cutoff rate decreased from 58% to 40%.
The surface resistivity of the coating film prepared according to the changing conditions of the coating speed was found to be about 10? 23? / ?.
These results show that as the bar coating speed increases, the thickness of the coating film becomes thinner, so that the visible light transmittance increases, the infrared cutoff rate decreases, and the surface resistance value increases.
When the transparent antifogging coated glass is manufactured from the above results, it is preferable to apply the coated glass having the surface resistance of 17 to 23? /? When the visible light transmittance is 75 to 80%.
In order to measure the adhesion and strength of the transparent conductive coating film for anti-fogging prepared in Experimental Example 2, the coating was scratched at a constant speed using a pencil (H to 9H) on the surface of the coating film at a load of 750 g, Respectively. FIG. 1 is a graph showing the result of a pencil hardness test on a coating film prepared according to Experimental Example 2 at a coating speed of 40 mm / s.
Referring to FIG. 1, it was confirmed that the coating film prepared according to Experimental Example 2 had a pencil hardness of about 5H.
2 and 3 are scanning electron micrographs showing the microstructure of the coating film prepared according to Experimental Example 2 at a coating speed of 40 mm / s.
Referring to FIGS. 2 and 3, the microstructure of the coating film prepared according to Experimental Example 2 was confirmed by an electron microscope. As a result, it was confirmed that Ag nanowires were uniformly coated on the entire glass surface. The reason why the Ag nanowire can be used to make a transparent conductive coating film with a low resistance is that the Ag nanowire is closely connected to each other as shown in the microstructure, and therefore the conductivity is excellent. Even when the nanoscale thin film is formed, .
It was confirmed that the coating film prepared according to Experimental Example 2 had a resistance of about 10? /? At a transmittance of 70% because it was densely connected without detaching Ag nanowires.
Coated glass coated with a transparent conductive coating composition for anti-fogging according to Experimental Example 2 in order to confirm the anti-fogging property, a general glass and a coated glass were respectively installed in the freezer and then measured.
When the freezer temperature was -17.7 ℃ and the external temperature was 22.5 ℃ and the relative humidity was about 31%, no fogging occurred on the surface of ordinary glass and coated glass.
However, when the relative humidity was about 44%, as shown in FIG. 4, condensation occurred on the general glass surface without coating, no fogging occurred on the surface of the coated glass, and humidity increased to about 61% The fogging on the general glass surface became worse, but the fogging on the coated glass was not observed (see FIG. 5).
As shown in FIG. 6, when the relative humidity was 63%, the internal temperature of the freezer was -17.1 degrees, and the external temperature was 24.4 degrees, the condensation continued to be severe on the ordinary glass surface, .
A performance comparison was carried out for Valentinis coated glass having a surface resistance of about 17 OMEGA / & squ & and coated glass coated with a transparent conductive coating composition for preventing fading according to Experimental Example 2. [
When the relative humidity was 54%, there was no fogging observed on the coated glass of Valentinis and on the coated glass surface of Experimental Example 2, but when the relative humidity was maintained at 63%, the coated glass of Valentinis and Experiment 2 And the fogging phenomenon on the glass surface was intensified at a humidity of 63% or more. Based on these results, it was confirmed that the anti-fogging properties of the coated glass of Valentinis and the coated glass of Experimental Example 2 were similar.
As described above, the coated glass coated with the transparent conductive coating composition for anti-fogging according to Experimental Example 2 has excellent adhesion to the coating film and exhibits a surface resistance of about 17? / Square when the visible light transmittance is 75% , Unlike coated glass which generates heat by generating electricity by applying electricity, the temperature of the freezer is -17.1 degrees, the external temperature is 24.4 degrees, and the relative humidity is less than 63% It was confirmed that the coated glass formed according to Experimental Example 2 had very good characteristics as a transparent conductive coated glass for preventing fogging.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, This is possible.
