| 摘 要： | 利用低温等离子体和UV诱导技术，制备具有较高生物相容性和亲水性的聚对苯二甲酸乙二醇酯(PET) 聚乙烯吡咯烷酮（PNVP）复合膜。利用衰减全反射傅里叶红外光谱(ATR-FTIR)、X射线光电子能谱(XPS)、原子力显微镜(AFM)对PET-PNVP复合膜表面的结构形态进行了系统表征，对影响接枝度的因素如引发剂浓度、UV辐射时间、单体浓度也做了系统分析。润湿性分析结果表明，接枝PNVP的PET膜表面亲水性得到了有效改善。体外血液相容性实验表明PET-PNVP复合膜具有较好的血液相容性。噻唑蓝比色法(MTT法)细胞毒性实验表明，PET PNVP复合膜没有细胞毒性。

| Abstract: | The preparation of poly(ethylene terephthalate)-poly(N-vinyl pyrrolidone)(PET-PNVP) composite films with higher hydrophilicity and biocompatibility was conducted by using the low temperature plasma treatment and UV-induced technique. The structure and morphology of PET-PNVP composite films were also characterized systematically through Attenuated Total Reflection Fourier Transform Infrared Spectroscopy (ATR-FTIR), X-ray Photoelectron Spectroscopy (XPS) and atomic force microscopy (AFM). Effects of various parameters such as initiator concentration, UV irradiation time and monomer concentration on grafting degree were also analyzed comprehensively. The wettability results showed that the hydrophilicity of PET-PNVP composite films had been improved considerably. Vitro blood compatibility experiments exhibited better blood compatibility for PET-PNVP composite films. The cytotoxicity of PET film was also detected via MTT method and the results showed that PET-PNVP composite film was non-toxic for cell. |
