Abstract
Hard coating solutions were prepared from glycidoxypropyl trimethoxysilane (GPTMS) and methacryloxypropyl trimethoxysilane (MPTMS) precursors with different molar ratios of 10:0, 9:1, 7:3, 5:5, 3:7, and 0:10, respectively, by the sol-gel method. The polycarbonate (PC) sheets were spin-coated, and cured at $130^{\circ}C$ for 3 h. The effect of the GPTMS:MPTMS molar ratios of the mixture was investigated on the properties of coating films. The highest pencil hardness and adhesion to PC sheets of coating films were found for solution with GPTMS:MPTMS molar ratio of 5:5. Also, the pencil hardness of coating films was increased with increasing the $H_2O$ content in the coating solutions.
