| 摘 要： | 讨论了烯丙胺单体微波等离子体连续放电对有机硅弹性体表面修饰的影响,通过改变温度和压力条件,研究其对表面修饰层化学性质、物理性质及生物相容性的影响.结果表明,温度、压力对表面修饰层胺浓度有较大的影响.随着压力增加,胺浓度减少;中等温度使胺浓度提高.根据细胞吸附、生长实验可知,烯丙胺等离子体修饰后,表面的生物相容性有很大的改善.

| Abstract: | A study is conducted on the microwave plasma surface modification of the silicone elastomer with allylamine to improve the biocompatibility of material. An investigation is made on the effect of plasma temperature and pressure on surface chemical composition, physical surface properties and biocompatibility of material. The results show that the temperature and pressure have a great influence on the chemical composition and structure of surface deposited layer. The surface biocompatibility was also greatly improved after modification; human skin fibroblasts adhered quickly and grew well on the modified silicone surface. |
