| 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PDMSbPS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PDMSbPS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PDMSbPS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PDMSbPS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13.2 μg/cm2。 |

| 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. |
