中文摘要：

以聚乙烯吡咯烷酮（PVP）为络合剂与醋酸锌[Zn（CH3COO）2]反应制得前驱体溶液，用静电纺丝法制备了PVP／Zn（CH3COO）2纤维，经煅烧得到具有微孔结构的氧化锌（ZnO）微／纳米纤维。对所制备纤维分别采用差热-热重分析、红外光谱分析、X射线衍射分析、扫描电镜等手段进行了表征。结果表明：PVP／Zn（CH3COO）纤维表面光滑，直径约300～700nm，经700℃煅烧后，可得到ZnO微／纳米纤维。

英文摘要：

Polyvinylpyrrolidone（PVP） used as a complexant was reacted with zinc acetate（ Zn（ CH3COO）2 to prepare precursor solution which was electrospun into PVP/Zn（CH3COO） 2 fiber from which ZnO micro/nanofibers with microhole structure can be prepared after calcinating. The obtained fiber was characterized by differential thermal gravimetric analysis （ DTG）, IR spectrometry （ IR）, X-ray diffraction analysis （ XRD ） and scanning electron microscopy （ SEM ）. The results showed that PVP/Zn （CH3COO） fiber had a smooth surface with a diameter in the range of 300 -700 nm, and the ZnO micro/nanofiber can be prepared from PVP/Zn（CH3COO） fiber after calcinating at 700℃.
