摘　　要：采用金属蒸汽真空弧(MEVVA)离子源将银离子和铜离子注入丙烯腈-丁二烯-苯乙烯共聚物(ABS)表面,并通过扫描电子显微镜(SEM)、X射线光电子能谱(XPS)和拉曼光谱(Raman)对该材料进行了表征,同时测试了改性后ABS树脂的抗菌性能。结果表明:离子注入后材料表面被侵蚀,且随着能量的增加粗糙程度变大;离子轰击使材料表面的化学键断裂、易挥发物质释出,并出现富碳层;离子注入后以氧化物的形式存在于材料表面;ABS树脂表面注入银离子和铜离子后具有优良的抗菌效果。Silver ions and copper ions are injected to the surface of acrylonitrile-butadiene-styrene copolymer（ABS） by metal vapor vacuum arc（MEVVA） ion source.The measurements of scanning electron microscopy（SEM）,X-ray photoelectron spectroscopy（XPS）,and Raman spectrum were used to analyze the samples.Moreover,the antibacterial property of the modified ABS was measured.The results show that surface of the samples implanted with ions was eroded,and the surface becomes rougher with the increase of injected energy.The chemical bonds of the material surface are fractured by ion bombarding,volatile matter was released,and a carbon rich layer appears; silver and copper ions existed as their oxides form in the surface of the material.ABS resin surface with silver ion and copper ion implantation shows excellent antibacterial effect.
