中文摘要：

在不添加掺杂剂的条件下,以吡咯为单体,三氯化铁为氧化剂,采用＂化学一步法＂合成了电磁功能化的聚吡咯/γ-Fe2O3复合物纳米结构.研究了不同氯化亚铁用量对聚吡咯/γ-Fe2O3复合物形貌、电学性能以及磁学性能的影响.结果表明,氯化亚铁的用量对聚吡咯/γ-Fe2O3复合物的形貌影响不大,都得到了聚吡咯/γ-Fe2O3复合物纳米球;然而,聚吡咯/γ-Fe2O3复合物纳米球的电学和磁学性能却明显受到氯化亚铁用量的影响.聚吡咯/γ-Fe2O3复合物纳米球的电导率和最大饱和磁化强度随着氯化亚铁用量的增加而增大,并在氯化亚铁用量增加到150 mg时达到最大值,分别为72.1 S/cm和10.07 A.m2/kg,实现了高电学性能和高磁学性能兼顾的电磁功能化导电聚合物纳米结构的制备.

英文摘要：

A ＂Chemical one-step method＂ （COSM） was used to prepare the electromagnetic functionalized polypyrrole/y-Fe203（PPy/T-Fe203） nanospheres without any dopant. In this method, FeC13 acted as an oxidant for the polymerization of pyrrole and as a source of T-Fe203, which also required the initial presence of Fe（ Ⅱ）, provided by the addition of FeCI2. In this paper, the amount of FeC12 had little effect on the morphology; however, the conductive and magnetic properties of PPy/T-Fe203 nanospheres were greatly affected by the amount of FeC12. The conductive and magnetic properties of PPy/T-Fe203 nanospheres increased and reached maximum values simultaneously with increasing amounts of FeC12. The resulting electromagnetic PPy/ y-Fe203 nanospheres show maximum conductivity of 72. 1 S/cm and saturation magnetization of 10. 07 A . m2/kg.
