| 摘 要： | 金属氧化物及其复合纳米纤维具有独特性能和潜在的应用价值,一直为人们所关注。本文提出了一种简便制备CuO/SiO2纳米复合纤维的新方法。即将静电纺丝技术与溶胶凝胶法结合,得到前驱体纤维;随后在适当的温度下热处理去除有机成分,最终得到直径150～200 nm的质量比为10%CuO/90%SiO2复合纳米纤维。使用SEM、TG-DTG、XRD、FT-IR、BET、UV-Vis技术手段对样品进行表征。SEM、TG-DTG、XRD、FT-IR结果表明该纤维的成分、形貌和晶相很大程度上受到煅烧温度的影响。BET结果表明该纤维的比表面积为141.95 m2/g,是纳米结构。光吸收测量结果发现该纤维的紫外光吸收性能随纤维晶相改变而改变。

| Abstract: | Metal oxide and metal oxide composite nanofibres have attracted great attention because of their unique properties and potential applications.A novel and simple method of preparing CuO / SiO2 nanofibers are proposed in this paper.CuO/SiO2(CuO:SiO2=10:90 wt%) nanofibers with diameters of 150 nm-200 nm were prepared by calcining precursor fibres,subtracting the organic ingredients.These precursor fibers were obtained by employing electrospinning technology together with sol-gel.The nanofibres were characterized by SEM,TG-DTG,XRD,FT-IR,BET and UV-Vis.SEM,TG-DTG,XRD and FT-IR results showed that CuO/SiO2 nanofibres′ morphology and crystalline phase were strongly influenced by the calcination temperature.The BET results showed that fibers are of nano structure,with a specific surface area of 141.95 m2/g.The optical absorption measurement results indicated that the ultraviolet light absorption performance was influenced by the crystalline phase. |
