摘　　要：结合溶胶凝胶法和静电纺丝工艺,制备了聚醋酸乙烯酯(PVAc)/TiO2杂化纳米纤维,经300～700℃的焙烧后得到TiO2纳米纤维.使用热失重分析仪(TGA)、X射线能谱分析仪(EDX)、X射线衍射仪(XRD)、扫描电子显微镜(SEM)对所制得纳米纤维的成分、晶型和形貌进行了表征,使用紫外可见光谱反射仪对纳米纤维的紫外透过率进行测试.结果表明:随着焙烧温度的升高,TiO2纳米纤维的成分、晶型和表面形貌都发生了明显的变化;400℃焙烧所得的TiO2纳米纤维具有最佳的抗紫外效果.The PVAc/TiO2 hybrid nanofibers were fabricated by sol-gel method and electrospinning process.The inorganic TiO2 nanofibers were prepared under 300-700℃ calcinations.The component,crystal form and surface morphology were investigated using Thermogravimetry Analysis（TGA）,Energy Dispersion X-Ray（EDX）,X-Ray Diffraction（XRD）and Scanning Electron Microscopy（SEM）.The UV-Vis transmittance was examined by UV-Vis spectra reflectometer.The results show that the component,crystal form and surface morphology are obviously changed as the increase of calcination temperature.The TiO2 nanofibers prepared under 400℃ has the best UV resistant property.
