溶液法改性高分子表面技术的研究 (Ⅰ)──改性高分子表面的结构和性质

A Study of Solution Technique for Modifying Polymer Surfaces() Surface Structure and Properties of Modified Polymer Surfaces

医用高分子材料的生物相容性问题逐步引起人们的重视［１］．除合成相容性好的材料外，另一个途径是对现有高分子材料进行改性以提高其生物相容性，其中表面改性因其对材料本体的影响小，成为医用高分子材料研究的一个热点．Ｒｕｃｋｅｎｓｔｅｉｎ［２］最早利用溶液法改...

This article reports a simple and effective method for modifying polymer surface. The modified polymer surfaces are characterized by 1H NMR, ESCA and water contact angle. The hydrophilicity of model polymer PS surface can be greatly increased. The PEO polar component is found to be concentrated at modified polymer filmair interface, which is benefit for the introduction of bioactive substances.
