| 摘 要： | 用两种不同气氛的辉光放电等离子体工艺对医用软质聚氯乙烯（ＰＶＣ）膜进行了表面改性研究。结果表明，聚合性气氛的等离子体改性效果明显优于非聚合性气氛。平整致密的聚合膜对ＰＶＣ增塑剂——邻苯二甲酸二辛酯的迁移和扩散起了阻挡作用，也使膜表面亲水性和表面张力极性成份增大，液固相界面张力减小，生物相容性得以改善。

| Abstract: | Surface modification of flexible polyvinyl chloride (PVC)films for medical uses was earrled out by plasma treatment and plasma polpoerization. Plasma polymerization was found to be more effective than non-pofymeric plasma treatment.Plasmapolymer covers the surface of PVC film a nd prevents the migration and diffusion of theplasticlzer.At the sa me time,the plasma polymer in creases the hydrophilicity and improves the biocompatibility of PVC film. |
