摘　　要：采用静电纺丝技术,以聚丙烯腈(PAN)和醋酸锌[Zn(Ac)2]为前驱物,制备了Zn(Ac)2/PAN复合纤维。利用六亚甲基四胺[(CH2)6N4]辅助的水热合成法,成功制备了具有异质结构的ZnO/PAN亚微米复合纤维。利用扫描电镜(SEM)、X射线能量色散光谱(EDS)、X射线衍射(XRD)、透射电子显微镜(TEM)和拉曼光谱(Raman)等对产物的形貌和结构进行表征。结果表明,ZnO纳米粒子均匀地生长在PAN纤维表面,形成了ZnO/PAN亚微米复合纤维。以罗丹明B为目标降解物,对光催化性能进行评价,结果表明,ZnO/PAN亚微米复合纤维具有良好的光催化活性。Polyacrylic nitrile（PAN）/zinc acetate（Zn（Ac）2） composite fibers were fabricated through electrospinning a precursor solution of PAN and Zn（Ac）2 in N,N-dimethylacetamide.After further hexamethylenetetramine（（CH2）6N4）-assisted hydrothermal treatment,ZnO/PAN submicron composite fibers were obtained.The morphology and structure of the product were characterized by SEM,EDS,XRD,TEM and Raman technique.The results showed that ZnO nanoparticles could be evenly grown on the surface of PAN fibers.By employing degradation of rodamine B（RB） as a model reaction,we found that as-fabricated ZnO/PAN submicron composite fibers possessed good photocatalytic activity.
