Abstract: Poly(tetrafluoroethylene) (PTFE) films were pretreated with remote argon plasma and subsequently exposed to air to create peroxides. The influence of the remote plasma treatment conditions on the peroxide concentration was investigated. It was shown that the maximum peroxide concentration on the surface of PTFE film was 2.87×10－11 mol /cm2 under the optimum plasma treatment conditions of 100 W，100 s and 20 cm3/min. Peroxide is known to be the species responsible for initiating graft polymerization. This study could provide the basic data for graft polymerization initiated by plasma.

摘要： 聚四氟乙烯膜经远程氩等离子体处理，暴露于空气中，在其表面生成了过氧自由基，研究了等离子体处理条件对生成过氧自由基的影响。结果表明，在远程氩等离子体放电时间100 s、放电功率100 W和氩气流量20 cm3/min的条件下，可获得的最大过氧自由基浓度是2.87×10－11 mol/cm2；过氧自由基可作为引发接枝聚合反应的活性点。
