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°.
