Properties of transparent color coating glass fabricated by sol-gel technology

Color sot was fabricated and coated it on glass substrate using sol-gel method. Silicate sot prepared by the use of commercially available tetraethoxysilane(TEOS), tetramethoxysilane (TMOS), methoxysilane(MTSO), phenytrimethoxysilane(PTMS) as a raw material of alkoxysilane family, and C.I. solvent red 122 and C.I. solvent yellow 82 as a organic dye, and C.I. pigment blue 28 and C.I. pigment red 26 as a pigment. Colored thin films were fabricated with changing the withdrawal speed by dip coating method, and heat treatment at 100 similar to 400 degrees C. The visible light transmittance of colored thin film was measured with UV/VIS spectrophotometer, the surface hardness measured by pencil test, the surface turbidity measured by haze meter, and the film thickness was measureded by Alpha-step surface profiler.
