【摘要】 本文用衰减全反射傅里叶红外光谱（ＡＴＲ－ＦＴＩＲ）和Ｘ射线光电子能谱（ＸＰＳ）对两种表面改性的耐药性能优良的医用橡胶样品进行了研究，结果表明两种样品表面层和体相组成完全不同，其表面层为氟化聚合物，体相为丁基橡胶。样品Ⅱ表面层氟的相对含量高于样品Ⅰ表面，且以ＣＦ２为主；在相同条件下进行氩离子刻蚀，样品Ⅱ表面层较样品Ⅰ表面层不同深度的Ｆ／Ｃ原子比的变化相对小。更多还原

【Abstract】 In this article,the drug resistance of two kinds of medical rubber whose surfaces have been modified were investigated by ATR FTIR and XPS.The experimental results show that the compositions of the two samples’surface and body are different.The surface is fluorinated rubber although the body is butyl rubber.The ratio of fluorine to carbon atom in sample Ⅱ 1 is higher than that in sample Ⅰ 1.The principal join between F and C is the form CF 2 in sample Ⅱ 1,but in sample Ⅰ 1 it is the form CF 2 and CHF .The change for F/C of the different depth in sample Ⅱ 1 was relatively less than that in sample Ⅰ 1 when they were etched by argon ion bundle in the same conditions.更多还原
