METHOD FOR REFORMING SURFACE OF POLY(ETHER-B-AMIDE) MULTI BLOCK COPOLYMER HAVING BIOCOMPATIBILITY SURFACE, AND POLY(ETHER-B-AMIDE) MULTI BLOCK COPOLYMER MADE BY THE SAME

摘要

The present invention relates to a method of surface modification of a polyether-amide multiblock copolymer film and to a polyether-amide multiblock copolymer film manufactured thereby. The method of surface modification of a polyether-amide multiblock copolymer film of the present invention comprises a fist dipping step of dipping a polyether-amide multiblock copolymer (PEBA) film in an evaporable solvent including light initiator; a step of removing the evaporable solvent existing on the dipped PEBA film; a second dipping step of dipping the light initiator-coated PEBA film in an aqueous solution including monomers; and a step of irradiating the PEBA film that is dipped in the aqueous solution including monomers with UV and graft-polymerizing monomer and the surface of the PEBA film, therefore the mechanical property of the conventional PEBA film is maintained and hydrophilic property and biocompatibility can be improved.
