摘　　要：通过原煤及氧化煤中的总酸性基的测定、FTIR分析及煤/PAN电导率变化研究,表明煤在氧化过程中,弱的醚键的水解及羧酸盐向羧酸的转化,增加了煤中的羧基和羟基含量。而羧基和羟基含量的增加有利于提高煤与苯胺的作用,从而提高复合材料的电导率,其值最高可达4.72×10-1S/cm。In this study,from the analysis of the total acidic groups in raw coal and oxidized coal,FTIR,and conductivity change,the hydrolytic decomposition of weak ether bands and the transformation of carboxylate to carboxylic acid during coal oxidation increased the total acidic groups（—OH and —COOH） in coal.The increase of —OH and —COOH groups was benefit to improve the action between coal and aniline,in turn,increased the conductivity of the complex with a maximum of 4.72×10-1 S/cm.
