利用分子设计对聚合物进行表面改性是在现有聚合物中引入新官能团的最有效的方法。这些官能团可以改善表面的憎水性、亲水性、生物相容性、抗静电性能、粘合性能等。其中,表面不污染的生物材料是许多研究人员感兴趣的领域。为了形成不污染的表面,曾采用多种水溶性聚合物进行表 Surface modification of polymers using molecular design is the most efficient way to introduce new functional groups into existing polymers. These functional groups can improve the surface hydrophobicity, hydrophilicity, biocompatibility, antistatic properties, adhesion properties and the like. Among them, the non-contaminating biomaterials are many areas of interest to researchers. In order to form a non-contaminating surface, a variety of water-soluble polymers have been used to form the table
