Preparation of Silica Hybrid Films on PMMA by Sol-Gel and Solvothermal Methods

Abstract:

Using solvothermal method to modify the surface of polymethyl methacrylate (PMMA), the silica films were prepared on it via sol solution and solvothermal treatment. Silica-based hybrid sol solutions were synthesized from tetraethoxysilane (TEOS) and methyltrimethoxysilane (MTMS). The obtained silica-based hybrid films consisted of the uniform particles around 40 nm in diameter observed by atomic force microscopy (AFM). The optical property was evaluated by the UV-Vis absorption spectra. The silica hybrid films prepared through this process showed good optical transmittance.
