| Research Abstract |
Silica thin films were prepared from perhydropolysilazane (PHPS) via exposure to the vapor from aqueous ammonia. PHPS-derived silica films had higher hardness, chemical durability and adhesion to plastics than alkoxide-derived silica gel films. Polycarbonate plates were coated with polymethylmethacrylate, and then with PHPS, followed by the exposure to the vapor from aqueous ammonia, which successfully increased pencil hardness from under 10B to H - 2H.
