| 摘 要： | 为了优化等离子体改性工艺,对聚丙烯板进行了常压空气等离子体处理.等离子体的产生采用了自制中频电源和平行板电极结构组成的介质阻挡放电系统.处理前后聚丙烯表面的微观结构、表面粗糙度和润湿性通过场致发射扫描电镜、原子力显微镜和接触角分析仪进行了分析.结果表明,等离子体处理后,聚丙烯板表面结构变粗糙且粗糙度增加了近5倍;表面接触角下降(或润湿性提高),并且等离子体剂量为1.5kJ的试样具有较好的润湿性和抗老化性能. |

| Abstract: | In order to optimize plasma surface modification process,polypropylene sheet was treated by atmospheric pressure air plasma.Plasma was created by dielectric barrier discharge(DBD) system,which consisted of home-made middle frequency power supply and parallel plane electrode configurations.The surface properties of the untreated and post-treated samples were studied by means of field emission scanning electron microscope(FE-SEM),atomic force microscopy(AFM) and water contact angle measurement.The results show that surface morphology becomes rougher and surface roughness increases nearly five times.Moreover,water contact angles decrease(or wettability improvement) and the treated sample at 1.5kJ plasma dose has better wetting and ageing properties. |
| Keywords: | power supply polypropylene plasma contact angle |
