Abstract

PDMSbPS copolymers with 32.1%, 40.7% and 49.5% PDMS contents were synthesized by macro initiator method, and the copolymer films were prepared by spincasting method. Surface morphologies and protein absorption performance of PDMSbPS copolymer films were studied. The results illustrate that all the investigated copolymer films have microphase structures, and bovine serum albumin (BSA) is slightly absorbed on the film surface. Thereinto, the PDMSbPS copolymer film with 40.7% PDMS content has maximum surface roughness and minimum absorbed amount of BSA. The BSA absorbed amount is 13.2 μg/cm2.

Key words

PDMS-b-PS; copolymer; antifouling coating; microphase structure; protein absorption
