| 摘 要： | 通过紫外光接枝方法,以丙烯酸为单体对低密度聚乙烯薄膜进行表面改性,然后用聚酰胺胺(PAMAM)分子对羧基化的聚乙烯表面进行修饰,制备了表面固定PAMAM树形分子的低密度聚乙烯薄膜。通过接触角测量,衰减全反射红外光谱,扫描电镜等方法的表征,证明丙烯酸成功接枝到聚乙烯薄膜表面,聚酰胺胺树形分子通过与羧基的结合形成团簇结构,反映了接枝链在薄膜表面的聚集状态。

| Abstract: | The carboxyl groups were introduced onto the surface of LDPE film by UV-induced photografting of acrylic acid and the grfated films were treated with the solution of poly(amidoamine)(PAMAM).The modified LDPE surfaces were characterized by ATR-FTIR,SEM and contact angle.It showed that the PAMAM was anchored on the film surface by reaction with carboxyl group.The granule morphology reflected the real aggregation state of grafted polyacrylic acid. |
