Preparation of superhydrophobic copolymer in carbon dioxide as a solvent and their applications

The present invention relates to a process for the preparation of superhydrophobic random copolymer with a carbon dioxide solvent, more specifically, the supercritical carbon dioxide using the solvent in the copolymerization solvent, and the second water-repellent performance by radically copolymerizing a hydrocarbon monomer and a silicon monomer or a fluorinated monomer having provided a method for producing a surface coating for the copolymer.
