以聚乙烯吡咯烷酮作为络合剂与醋酸锌混合,并且加入适当催化剂,制得纺丝液。采用静电纺丝的方法,制得聚乙烯吡咯烷酮/醋酸锌复合纤维,通过热处理得到氧化锌纤维。对所制得的纤维成分、形貌、晶粒大小,分别采用X射线粉末衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)等分析测试手段进行表征。实验结果表明,500℃下煅烧得到表面粗糙、充满细小管道的纯氧化锌纳米纤维,平均晶粒尺寸5nm,拥有超高比表面积。
With polyvinylpyrrolidone as a complexing agent and zinc acetate were mixed, and adding a suitable catalyst to prepare a spinning solution. Electrospinning method is used to obtain polyvinylpyrrolidone / zinc acetate composite fiber, obtained by heat treatment of zinc oxide fiber. The fiber composition, morphology and grain size were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The experimental results show that pure zinc oxide nanofibers with rough surface and small diameter are calcined at 500 ℃ with average grain size of 5nm and super high specific surface area.
