Porous films were prepared on the base of the cardo polyimide soluble in organic solvents and modified with fluorocontaining organosilicon copolymers. The fluorinated organosilicon copolymers with various molecular weights were used as hydrophobic modifiers. It was shown that addition of modifiers leads to formation of porous structure with monomodal size distribution. Modification of the polyimide with copolymers in combination with the surface structuring resulted in formation of the highly hydrophobic porous films with contact angle 137°.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
