| 摘 要： | 以苯胺和过硫酸胺为原料,采用原位聚合方法合成了聚苯胺/碳化钨(PANI/WC)导电复合材料。研究了反应体系中碳化钨的含量对复合材料电导率的影响,确定了较佳的聚合条件,并且通过FT-IR、XRD、XPS和DSC-TGA等手段对复合材料的结构和性能进行了表征和分析。结果表明:碳化钨(WC)的加入提高了聚苯胺的电子导电性能,复合材料中聚苯胺组分为无定型,WC的晶型在反应前后并未发生变化,复合材料的热稳定性好并且质子化程度更高。

| Abstract: | The polyaniline/tungsten carbide(PANI/WC) composite is synthesized by in situ polymerization using aniline and ammonium persulfate as starting materials.The conductivity on the tungsten carbide content is studied in detail,and the proper polymerization condition is obtained.The structure and stability of the composites are characterized by FT-IR spectra,XRD,XPS and DSC-TGA analysis.The results show that the electrical conductivity is enhanced obviously due to the introduction of WC to PANI.PANI in the compo... |
