| 摘 要： | 利用自行研制的直流脉冲电源和交流脉冲电源产生等离子体, 分别对聚四氟乙烯进行了表面改性研究.在放电电压、占空比、工作气压、工作气氛、处理时间相同的情况下,探讨了直流脉冲和交流脉冲等离子体对样品改性效果的不同影响;通过接触角测量、扫描电镜(SEM)等手段对未处理的、直流脉冲和交流脉冲作用后的亲水性、表面形貌进行了检测和分析.结果表明:交流脉冲等离子体对PTFE的改性效果优于直流脉冲等离子体.

| Abstract: | PTFE surface modification employing 100kHz AC and DC pulse plasma generators were researched. In the same condition of discharge voltage, duty ratio, pressure, gas, worked time, the effects of AC pulse plasma and the DC pulse plasma on modification of sample were investigated. The hydrophilicity and surface morphology were discussed using the contact angle and SEM analysis. Measurement results show that the PTFE surface modifation effect by AC pulse plasma is better that that by DC pulse plasma. |

| Keywords: | AC pulse plasma DC pulse plasma PTFE Surface modification Hydrophilicity |
