摘要
为提高聚四氟乙烯(PTFE)膜的粘接性能,研究了氧气等离子体处理对PTFE膜剥离强度和水接触角的影响,并比较了氧气、氮气和氩气等离子体处理PTFE膜粘接强度的差异,借助X射线光电子能谱仪、扫描电子显微镜和原子力显微镜测试了等离子体处理前后PTFE膜表面元素、形态和粗糙度的变化。结果表明:氮气等离子体处理的PTFE膜,其剥离强度较未处理的PTFE膜提高了539.8%,水接触角提高了11.4°,达120.4°;当放电量低于36 kJ时,经氧气等离子体处理的PTFE膜剥离强度随放电量的增加呈指数增加,继续增加放电量时,PTFE膜表面形成了凹凸沟槽的荷叶形貌,该荷叶形貌决定了膜粘结性和疏水性的强弱。
In order to improve the adhesion performance of polytetrafluoroethylene(PTFE)film,this research studied the effect of oxygen plasma treatment on the stripping strength and water contact angle of the film surface,and compared the adhesive strength of films treated by oxygen,nitrogen and argon plasma.In addition,the changes of surface element,morphology and roughness were measured by means of X-ray photoelectron spectroscopy,scanning electron microscopy and atomic force microscopy.The results show that the stripping strength is increased by 539.8%and the contact angle is increased by 11.4°(up to 120.4°)when the PTFE film is treated with nitrogen plasma.When the discharge magnitude is below 36 kJ,the stripping strength of the oxygen-treated PTFE film increases exponentially with the increase of discharge power.When the discharge magnitude is higher,the pattern of lotus leaf with the concave and convex grooves is formed on the PTFE film surface,and the shape of lotus leaf of PTFE film determines the film adhesion and hydrophobicity.
