摘要

本工作通过等离子体预处理的方法，实现了丙烯酰胺（AM）与聚四氟乙烯（PTFE）的接枝共聚合。接枝后的PTFE表面性能同PAM一致。聚合动力学研究发现，接枝首先由过氧化自由基引发，随着反应的进行过氧键断裂生成烷氧自由基。随后的聚合是由烷氧自由基引发的。

Abstract

The peroxide free radicals exist in the surface of PTFE films treated by plasma. These free radicals can react with AM to form a grafted layer. XPS analysis showed that there are O and N elementary on PTFE surfaces after grafting. The surface energy of grafted layer is 35-40 dyn/cm as same as that of polyacrylamide. The amount of grafted AM is affected by plasma treating time and postpolymerization time. The postpolymerization is very complicated.
