Preparation and Properties of Conducting Polyaniline Core-Shell Composite

Abstract

本文中通过原位聚合方法成功制备了核壳型导电聚苯胺复合材料。利用扫描电子显微镜，傅里叶红外光谱和X射线衍射等检测分析手段研究了材料的微观形貌和结构；利用热失重分析检测手段对材料的热稳定性进行了研究。实验结果表明通过原位聚合成功制备了核壳结构的复合材料，并且复合材料的综合性能与单一种类材料相比有较大的提升，成功的将芴的电子传输特性和聚苯胺的热稳定性结合在了一起。 The purpose of the work is to fabricate successfully PANI via preparing core-shell structure compo-site materials through in situ polymerization. The morphology, structure crystallinity, and thermal stability of synthesized composite were investigated by Fourier Transform Infrared (FTIR), X-ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). Results of the experiment indicated that core-shell structure material is successfully synthesized via in situ polymerization, and compared to signal kind material, comprehensive performance of composite is greatly improved. Electron transport properties of fluorene and thermal stability of PANI are successfully combined together.
