Outline of Final Research Achievements

In order to use polycarbonate (PC) for resin windows for vehicles, the surface hardness and the durability were improved through the formation of SiO2 by photochemical modification method. The water repellency and the antistatic property were examined as additional functions. As a result, by only photochemical process, Taber abrasion test of ΔH1000≦2%, heat resistance for 120°C 3 h, super water repellency with a water droplet contact angle of 150° or more, and antistatic resistance equivalent to inorganic glass were obtained.
