The synthesis of novel fluorine-containing random polymer and application in modification of solid surfaces

The novel fluorine-containing random polymers, poly (2, 3, 4, 5, 6-pentafluorostyrene)-r-poly (4-vinyl benzocyclobutene) random copolymer was synthesized, which can effectively decrease the surface energy and provide a good corrosion protection for some metals. Additionally, textured silicon was fabricated by an optically assisted electrochemical etching process to study the effect of the random copolymer modification on the binary geometric structures of the solid surface. After modification the superhydrophobic property can easily be obtained, which show long-term stability and good superhydrophobicity in corrosive solutions over a wide pH range, including acidic and basic solutions.
