摘要/Abstract

摘要： 通过静电纺丝技术制备聚丙烯腈（PAN）/二氧化钛（TiO2）-氧化石墨烯（GO）杂化纤维膜，经煅烧处理后，通过扫描电子显微镜（SEM）、X射线衍射仪（XRD）、热重仪（TG）和分光光度计等仪器，分别对杂化纤维的形貌特征、结晶性能、热性能和光催化降解能力进行分析。结果表明，钛酸四丁酯（TBOT）水解产物经煅烧处理后，转变为锐钛矿型TiO2；随着TBOT添加量的增多，纤维直径逐渐减小，最小可达25 nm；TBOT的加入可以改善纤维的热稳定性；降解次甲基蓝实验可知，随着TBOT加入量的增大，样品的光催化性能有所提高；TiO2-GO/PAN杂化纤维膜经煅烧后可作为一种光催化剂。

Abstract: Polyacrylonitrile (PAN)/titanium dioxide (TiO2)-grapheneoxide (GO) hybrid fiber membranes were prepared by an electrospinning method, followed by calcination. The morphology, crystallization behaviors, thermal properties and photocatalytic performance of the hybrid fibers were investigated by scanning electron microscopy, X-ray diffraction, thermogravimetic analysis and spectrophotometry. The results indicated that tetrabutyltitanate hydrolysateswerewell converted to anatase TiO2 after calcinations. The fiber diameter decreased gradually to a minimum value of 25 nm with an increase of tetrabutyltitanate content.Moreover, the addition of tetrabutyltitanate improved the thermal stability of the fibers. In addition, a methine blue degradation experiment confirmed that the photocatalytic activity of the fibers was improved due to the addition of tetrabutyltitanate. Summarily, the PAN/TiO2-GO hybrid fiber membranes developed by this work can be used as a photocatalyst.
