【摘要】 利用A r气氛等离子体为引发手段对PTFE膜进行表面处理,最终实现了在PTFE膜表面接枝丙烯酸。通过XPS和ATR-FT IR对改性膜进行表面分析,表明在PTFE膜的表面形成一层聚丙烯酸(pAA c)薄膜。实验证实PTFE-g-pAA c膜的表面亲水性及表面稳定性较好,克服了等离子体改性效果不稳定的缺点。本研究拓展了PTFE膜材料在其他各相关领域的应用,具有较好的实用价值。更多还原

【Abstract】 The polyterafluoroethylene(PTFE) films were subjected to further surface modification with Ar plasma,and the acrylic acid(AAc) was grafted on the surface of PTFE.The modified films were analyzed by XPS and ATR-FTIR,which showed that the pAAc films have formed on the surface of PTFE films.The study confirmed that PTFE-g-pAAc films have a great improvement in surface wettability and surface stability,which expands the application of PTFE films in other relevant fields.更多还原
