摘　　要：利用大分子引发聚合法制备出了PDMS摩尔含量分别为32.1%,40.7%和49.5%的PDMS-b-PS共聚物,利用旋转涂膜法制备了共聚物薄膜。研究了不同PDMS含量下,3种PDMS-b-PS共聚物膜的表面形貌以及蛋白吸附性能。结果表明,所制备的3种PDMS-b-PS共聚物膜都呈现出良好的表面微相分离结构,并且对牛血清白蛋白(BSA)的吸附量均很小,其中PDMS含量为40.7%的PDMS-b-PS共聚物膜表面结构的粗糙度最大,对牛血清白蛋白的吸附量最小,为13.2μg/cm2。PDMS-b-PS copolymers with 32.1 %, 40.7 % and 49.5% PDMS contents were synthesized by macro initiator method, and the copolyrner films were prepared by spin-casting method. Surface morphologies and protein absorption performance of PDMS-b-PS copolymer films were studied. The results illustrate that all the investigated copolymer films have micro-phase structures, and bovine serum albumin （BSA） is slightly absorbed on the film surface. Thereinto, the PDMS b-PS copolymer film with 40.7% PDMS content has maxi- mum surface roughness and minimum absorbed amount of BSA. The BSA absorbed amount is 13.2 μg/cm2.
