以聚丙烯腈(PAN)和醋酸锌[Zn(Ac)2]为前驱体,采用静电纺丝技术制备了不同Zn(Ac)2含量的PAN/Zn(Ac)2复合纳米纤维.利用场发射扫描电镜(FE-SEM)、傅里叶变换红外光谱(FT-IR)、X射线衍射(XRD)、热重分析(TG)和X射线能量色散光谱(EDS)对各种纤维膜的结构和性能进行表征.结果表明,复合纤维的直径以及直径分布随Zn(Ac)2含量的增加先减小后增大;Zn(Ac)2的加入并没有改变PAN的化学结构;PAN/Zn(Ac)2复合纳米纤维的结晶度以及晶粒尺寸随Zn(Ac)2含量的增加而减小;Zn(Ac)2含量对复合纤维的分解温度及残留物的质量影响较大;复合纤维膜在空气环境中高温煅烧后得到的物质为ZnO.
