| 摘 要： | 采用Ar等离子体技术对聚四氟乙烯(PTFE)片材表面预处理,再用热接枝的方法引发甲基丙烯酸缩水甘油酯(GMA)对其表面进行接枝改性.考察不同等离子体处理条件及接枝单体体积分数对PTFE与钢粘接强度和与水接触角的影响.同时,对接枝后的PTFE用x射线光电子能谱(XPS)进行分析表征.研究结果表明,GMA单体成功地接枝到PTFE表面,当等离子体处理时间为5min、功率为50W、气氛压力为50Pa、单体接枝体积分数为20%时,改性后的PTFE与钢的拉剪强度由处理前的24.6N·cm-2增加到处理后的284.6N·cm-2.

| Abstract: | The surface of Polytetrafluoroethylene (PTFE) sheet is pretreated using Argon plasma technique,and then the surface is modified by thermal-induced graft polymerization of glycidyl-methacrylate (GMA).The effects of different plasma treatment conditions and different monomer volume fraction of GMA on the bonding strength between PTFE and steel and the water contact angle of grafted PTFE are studied.Meantime,the grafted PTFE is characterized by means of X-ray Photoelectron Spectroscopy (XPS).The results show that GMA is successfully grafted onto the surface of PTFE,and the bonding strength between the grafted PTFE and steel is increased from 24.6 N·cm-2 to 284.6 N·cm-2 when the plasma treatment time is 5 min,the power is 50 W,the pressure is 50 Pa and the grafted monomer volume fraction of GMA is 20%. |
