在聚丙烯腈(PAN)、N,N-二甲基甲酰胺(DMF)体系中加入钛酸四丁脂水解溶胶,通过静电纺丝技术得到纳米纤维膜,经预氧化、炭化、活化制备出TiO2/活性炭复合纳米纤维膜.采用扫描电子显微镜、X射线能谱、热分析、傅里叶红外光谱、X射线衍射以及测定Zeta电位和表面接触角等手段对TiO2/活性炭复合纳米纤维膜进行表征.结果表明,当V(PAN)∶V(DMF)∶V(Ti(OH)4溶胶=3∶17∶3时,可制得纤维直径为600～700nm的TiO2/活性炭复合纳米纤维膜.纳米TiO2在TiO2/活性炭复合纳米纤维膜中分布均匀,晶型结构易于控制；TiO2/活性炭复合纳米纤维膜有较强的光催化活性和吸附活性,可以作为环境功能材料使用.
