摘要
煤基聚苯胺 (CBP)是一类有着广阔应用前景的导电填料。本文用热掺杂法制得DBSA掺杂态CBP ,并采用熔融共混工艺 ,制备出HDPE/CBP DBSA导电复合材料。结果表明 :70℃下退火2h ,DBSA :CBP =1 6 (质量比 ) ,该条件下电导率为 0 179s/cm ;红外光谱说明DBSA对CBP起到了较好的掺杂作用。复合体系中CBP -DBSA含量为 13%时 ,复合材料的电学。
The coal-based polyaniline(CBP) is one of the conductive polymer fillers with widely application . CBP-DBSA are preparated by thermol doping method, and melt blends are applied to prepare HDPE/CBP-DBSA conductive composites. The results display: when the temperature is 70℃,the annealing time is 2h, DBSA:CBP=1.6(weight ratio), and the conductivity is 0.179s/cm..Infrared spectrum shows DBSA plays a better doping role on CBP. When the CBP content are 13% in composite system, both electric properties and mechanical properties of polymer composite will meet expectation.
