共沉淀-熔盐法合成的BaFe8(Ti0.5Mn0.5)4O19纳米颗粒掺杂在邻甲苯胺的酸性溶液中,采用原位复合法制备导电聚邻甲苯胺磁性复合颗粒.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15nm左右的晶粒分散于聚邻甲苯胺(POT)基体之中,一定程度上减小了铁氧体纳米粒子的团聚.但是BaFe8(Ti0.5Mn0.5)4O19与POT之间不存在化学键合作用,此现象与其它文献报道不一致.POT/BaFe8(Ti0.5Mn0.5)4O19复合颗粒的导电性随POT含量的增加而增强,而比饱和磁化强度随之下降.
