摘　　要：利用表面引发技术,自组装合成新的原子转移自由基聚合(ATRP)表面引发剂,并引发4-乙烯基吡啶(4-VP)聚合.制备了功能性的聚4-乙烯基吡啶(PVP)膜,同时在表面配合过渡金属Cu2+和Ag+,用NaHB4还原后得到表面含有金属纳米粒子的复合膜,并利用XPS,FT-IR,AFM和接触角测试了其结构与性能.结果表明,聚合物金属配合物中的金属离子已经被还原,其纳米粒子尺寸直径约为170 nm.Atom transfer radical polymerization （ATRP） initiator was assembled on silicon wafer to initiate 4-vinylpyridine polymerization by surface initiated technique, a functional PVP brush was prepared. The metal complexes of Cu^2＋ and Ag^＋ with polyvinylpyridine （PVP） were formed, and the metal complexes were reducted to metal nanoparticles with NaBH4. The structure and properties were proved by using XPS, FT-IR, AFM and water contact angle. The result shows the metal complexes of PVP have been reduced, the size of metal nanoparticles is about 170 nm.
