Abstract
The present invention discloses a method of preparing a terpolymer-doped polyaniline super-hydrophobic composite anticorrosive paint. The method includes: firstly by adopting solution polymerization, stirring a hydrophilic vinyl monomer, a fluorine-containing acrylate monomer and an oil-soluble initiator in a solvent evenly and carrying out a reaction for a period of time, then adding a functional acrylic monomer or long-chain acrylate monomer as a third monomer for further reaction for a period of time to obtain a fluorine-containing terpolymer surfactant; then mixing the fluorine-containing terpolymer surfactant with an aniline monomer and an oxidant evenly, and carrying out a reaction for a period of time to obtain super-hydrophobic polyaniline; and finally dispersing the prepared super-hydrophobic polyaniline evenly in a resin matrix to prepare the polyaniline super-hydrophobic composite anticorrosive paint with an excellent anticorrosive performance.
