摘要/Abstract

摘要： 为了制备具有良好生物相容性的植入性人造头发，采用液相原位聚合法制备了聚吡咯/涤纶单丝，并对其性能进行测试。采用扫描电镜、红外光谱、X射线光电子能谱等测试手段，来确定聚吡咯的存在，分析了碱减量处理时间对聚吡咯镀膜量的影响，同时测试了碱减量处理及吡咯聚合前后单丝力学性能的变化。并对单丝的细胞相容性进行测试。结果表明，无论是否经过碱减量处理，都能够在涤纶单丝表面聚合生成聚吡咯，但经过碱减量处理的单丝聚吡咯含量较高。单丝经碱减量处理后力学性能有所降低，而吡咯聚合后力学性能升高。经吡咯处理后单丝的细胞相容性有所提高。

关键词: 聚吡咯, 涤纶单丝, 碱减量, 细胞相容性

Abstract: In order to prepare artificial hair implantation which has good cytocompatibility, polypyrrole/polyester monofilaments were prepared by liquid in-situ polymerization and its performance was tested. Scanning electron microscope、FTIR spectroscopy and X ray photoelectron spectroscopy methods were used to investigate the existence of polypyrrole and analyze the influence of alkali treatment on the polypyrrole content. Meanwhile, the mechanical properties of monofilaments after alkali treatment and polypyrrole polymerization were analyzed. The cytocompatibility was tested. The results show that polypyrrole can be formed on the surface of polyester monofilaments whether for treatment with alkali or not, but polypyrrole content is higher on the alkali-treatment monofilament. The mechanical properties of monofilament have been decreased after alkali treatment, but they were increased after polypyrrole polymerization. Furthermore, the cytocompatibility of polyester monofilaments has been improved after pyrrole polymerization..

Key words: polypyrrole, polyester monofilament, alkali weight-reduction, cytocompatibility
