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.
