用 MEVVA 源将银离子注入 ABS（Acrylonitrile Butadiene Styrene）树脂表面，研究在注入剂量为1.0×1016 ions/cm2、注入能量由5 keV 到30 keV 材料的抗菌性。通过 X射线光电子能谱（XPS）及拉曼（Raman）光谱对样品表面进行了表征，并测试样品的疏水性和抗菌性。结果表明：载能离子导致 ABS树脂表面部分化学键断裂，并出现失氢、富碳，而银以离子形式存在其氧化物中；材料表面的接触角变大，由亲水性材料变为疏水性材料；银离子注入后材料具有良好的抗菌性能，抗菌效果随着离子注入能量的增加呈现降低趋势。

In this paper, silver ions were implanted into ABS resin surface by MEVVA source. The antibacterial property of the materials was investigated as the implantation dose is 1×1016 ions/cm2 and implantation energy changes from 5 keV to 30 keV. X-Ray photoelectron Spectroscopy(XPS) and Raman spectra measurements were used to analyze the compositions of the surface. Then hydrophobic property and antibacterial property were measured. The results show that the ionic forms of silvers exist in its oxides. Some chemical bonds of modified surface were destroyed by implanted silver ions. The silver implantation makes ABS resin lose hydrogen atoms and surplus carbon atoms, namely, it causes the appearance of carbon-rich layer. Water contact angle was found to be increased by modification, in other words, the modified surface changed from hydrophilicity to hydrophobicity. The experiment indicates that the material possesses excellent antibacterial property after implantation and the antibacterial effect decreases with the increase of implantation energy.
