【Abstract】 SiO₂ sol-gel coatings tend to crack during drying. In this paper, the main aspects of the preparation of SiO₂ sols were systematically investigated, including synthesis temperature, reaction progress, reactant conversion, and particle size of the sols. Silane and polyamide acid were used to modify these sols in order to obtain crack-free organic-inorganic hybrid films.更多还原
