Abstract
Silsesquioxanes derived from (γ-Methacryloxypropyl) trimethoxysilanes (M-S) and their blends modified with tetraethoxysilane (TEOS) (MST)were prepared by sol-gel process. In order to understand the silsesquioxanes film properties, coating films based on M-S and MST (m-M-S and m-MST) as ormosils were prepared. The film properties were characterized and studied with a scanning probe microscope (SPM) device, scanning electron microscope (SEM) device, differential scanning calorimetry (DSC), thermogravimetry analysis (TGA), UV-VIS-NIR scanning spectrophotometer (SSP), nano-indenter (NI) device. The result showed that the film is a kind of organic-inorganic hybrid nanocomposites coating, the transmittance is 98%-99% in 345-2500 nm wave band, the film with 20% TEOS fraction has the optimum mechanic and corrosion resistance properties.
