摘　　要：在樟脑磺酸的手性诱导作用下,在硅藻土表面原位聚合苯胺得到手性聚苯胺改性硅藻土复合材料,利用红外吸收光谱(FTIR)和扫描电子显微镜(SEM)对复合材料的结构进行表征,表明苯胺在硅藻土表面进行了原位聚合,聚合产物呈现纳米棒状态。通过测试复合材料的循环伏安特性曲线(CV)表征材料的电化学性能,对比了在不同手性聚苯胺/硅藻土配比以及不同时间条件下改性材料的性能差异。结果表明:随着苯胺聚合量的增大以及反应时间的增加,复合材料的电化学性能会呈现先增大后减小的趋势。Composite materials of diatomite modified by chiral polyaniline were obtained by polymerized aniline in the surface of diatomite by in-situ polymerization under chiral induction by camphor sulfonic acid.FTIR and SEM were used to characterize the microscopic structure of composite material,and the results showed that aniline was polymerized in the surface of diatomite by in-situ polymerization successfully,with these polymers being nanorods.Circulation current-voltage characters curves（CV） of composites prepared under different reactant dosage and polymerization time were tested,indicating that with increasing of aniline dosage and polymerization time,the electrochemical properties of composite materials can present first increase,then decrease trend.
