Wear, thermal, and physical properties of fluorine-containing polyimide/silica hybrid nanocomposite coatings

This study prepared fluorine and SiO 2 particles containing organic–inorganic hybrid polyimide nanocomposite coatings (PISFs) with inorganic content in the range of 5–20% in pure polyimide solutions via the sol–gel process. Polyimide hybrid structures containing fluorine and SiO 2 particles were synthesized by using perfluorooctyltriethoxysilane and tetraethyl orthosilicate. These formulations were applied on aluminum sheets by using a 75 μm...
