Preparation and Characterization of Precursor Solution for a Hard Coating Silica Film
The synthetic condition for the crack-free and transparent silica film formation was optimized in terms of starting materials for the precursor solution as well as preparation method of the silica film. A silicate framework of the precursor solution was investigated by infrared spectroscopy (IR) in the process of hydrolysis and condensation. The extent of the condensation in the intermediates was elucidated by gel permeation chromatography (GPC) and 29Si-NMR spectroscopy. The hard coating films were characterized by IR, scanning electron microscope (SEM), thermo gravimetric analyzer (TGA) and differential scanning calroimeter (DSC).
