| 摘 要： | 首先对聚对苯二甲酸乙二醇酯(PET)薄膜进行氧等离子体预处理,然后通过原位化学氧化聚合法使得吡咯单体在PET薄膜表面沉积聚合,制备了聚对苯二甲酸乙二醇酯/聚吡咯(PET-PPy)复合膜。通过原子力显微镜、X射线光电子能谱仪、ζ电位测试对经不同时长的氧等离子体预处理的PET薄膜进行表征;利用扫描电子显微镜、耐磨性实验和表面电阻测试对PET-PPy复合膜磨损前后的表面形貌和电阻进行分析与表征。结果表明,氧等离子体预处理显著增强了PET-PPy复合膜界面粘附性。氧等离子体预处理使PET薄膜表面粗糙度增大、电负性显著增强。特别地,当预处理时间为120s时,薄膜表面电负性明显增强,此时PET-PPy复合膜磨损后的电阻值变化最小,表明PET薄膜与PPy功能层界面粘附强度得到明显增强。

| Abstract: | Polyethylene terephthalate (PET) films were pretreated with oxygen plasma firstly. Then, polypyrrole (PPy) functional layers were polymerized on the surface of PET films to form PET-PPy composite films by in situ chemical oxidation polymerization method. Atomic force microscopy, X-ray photoelectron spectroscopy and zeta potential measurement were used to characterize PET films pretreated with oxygen plasma for different durations. The surface morphology and electrical resistance of PET-PPy composite films before and after abrasion were investigated by scanning electron microscopy, abrasion resistance and sheet resistance measurements. The results showed that the interfacial adhesion of PPy functional layer to PET film is significantly improved by oxygen plasma pretreatment. The increased surface roughness and the enhanced electronegativity are the leading factors for the improved adhesion strength. In addition, the optimal pretreatment duration is 120 s. |
