S1108-1-5 Functional evaluation of the inorganic system glass coating film

Abstract

The inorganic system glass coating film was developed as a painting protection film for the car. The glass film adds hydrophile and the resistance to ultraviolet rays to various materials. However, the functional evaluation of the glass film is difficult because the film thickness is about 20 nm. I tried the reflectivity measurement of existence and a characteristic of the glass film by the spectrophotometer. The glass film's reflectance has changed by the uv in about 10%. The glass film is expected that there is a characteristic of reflecting and scattering for the uv. In addition, I investigated the mechanism of coating the glass film. I made the electroplating system. I found the reflectivity change that the electroplating film is similar to the glass film. So, I found that boric acid silica has the electric-charge of the plus and the glass film is coated by the principle of electroplating.
