| 摘 要： | 本文以聚砜为基材，采用共混法，利用聚原酸酯-b-聚乙二醇嵌段共聚物中聚乙二醇段表面自由能高的特性，对材料表面进行改性，用扫描电子显微镜对表面微形态进行观察，以接触角来评价材料表面的亲疏水性，研究结果表明，材料表面出现微观相分离结构，且因聚乙二醇段富富集于表面，材料表面的亲水性得以提高。

| Abstract: | The general method modifying hydrophobic polysulfone to produce highly hydrophilic surfaces was developed. This method is the blend technique. We used scanning electronic microscopy to examine the phase behavior of A-B diblock copolymer of poly(ortho esters)-b-poly(ethylene glycol). Because PEG has high surface energies in copolymer, PSF membranes were modified and improved the surface hydrophilicity and hemocompatibility. |
