Investigations on self-cleaning/UV-blocking films are quickly increased because recently the film has been used in show windows, high-rise building, and car. In this study, we used various fillers like TiO2 and SiO2-coated TiO2 to control UV-blocking and hydrophilicity for film prepared using those fillers and analyzed their optical property such as contact angle, UV-absorbance, transmittance, and haze. The hydrophilicity of the coated film gives different contact angle depending upon filler/UV resin ratios. Optical properties (transmittance and haze) can be explained based on particle amounts in film. Also, UV-absorbance was sensitively changed by contents of TiO2 or SiO2-coated TiO2 in film. |
