采用原位复合法制备导电聚苯胺磁性复合颗粒,借助FTIR、XRD、UV-Vis、TEM和VSM等分析手段研究了复合粒子的形貌、结构及其光、电和磁性能.结果表明:BaFe8(Ti0.5Mn0.5)4O19以约12 nm的粒径分散在聚苯胺基体中,聚苯胺与铁氧体之间存在化学键合作用,一定程度上减小了铁氧体纳米粒子的团聚;PANI/BaFe8(Ti0.5Mn0.5)4O19复合颗粒同时具有导电性和磁性能,其导电性随聚苯胺含量的增加而增强,而比饱和磁化强度随之下降;当聚苯胺含量为54.91%时,复合颗粒电磁学性能为He=92 kA/m,σs=11.54 Am2/kg,σr=4.97 Am2/kg,σ=13.1 S/m.
