| 摘 要： | 尝试用Ar等离子体技术与紫外光照射技术相结合的方法,在无光引发剂的条件下、在PMMA表面接枝丙烯酰胺（AAm）,以改善材料表面的抗静电性能。探讨了等离子体预处理时间、放电功率、气体压强、AAm单体浓度和紫外照射时间对材料表面电阻率的影响。通过ATR-FTIR和扫描电子显微镜（SEM）分析,研究了PMMA接枝AAm前后表面性能和表面形貌的变化。抗静电性能测试结果表明,接枝丙烯酰胺可以使PMMA材料的抗静电性能显著增强,表面电阻率下降了3～5个数量级。

| Abstract: | Acrylamide（AAm） was grafted onto the surface of PMMA by Ar plasma pretreatment and UV-induced graft polymerization without photo-initiator to enhance antistatic property of PMMA plates.The effect of plasma-treatment time,plasma discharge power,Ar pressure,AAm monomer concentration and UV irradiation time was studied in the experiment.The surface compositions and microstructure of AAm grafted PMMA plates were studied by ATR-FTIR and Scanning Electron Microscopy（SEM）.Results of measuring the surface resistivity indicated that the surface resistivity of AAm-grafted PMMA plates decreased significantly by 3～5 orders of magnitude and the antistatic property was improved remarkably. |
