采用溶胶-凝胶法和静电纺丝法制备了以聚乙烯吡咯烷酮（PVP）纤维为基体的TiO 2一维纳米粒子。TEM分析表明，纳米TiO 2颗粒链位于PVP纤维的中部，沿纤维方向沿着呈线性分散，这是由于高电场引起的极化和取向效应所致。随着溶胶-凝胶前驱体浓度的增加，纤维中纳米粒子的直径从60 nm减小到13 nm。这种复合纳米材料在光致发光（PL）、电致发光（EL）和非线性光学器件、平板显示器、太阳能光电阴极等方面具有潜在的应用前景。
One-dimensional TiO2nanoparticles within polyvinylpyrrolidone (PVP) fiber matrices were prepared via coupling sol–gel method and electrospinning. TEM analysis indicated that TiO2nanoparticles chain was in the middle of PVP fiber and dispersed linearly along the fiber direction, which originated from the effect of polarization and orientation caused by high electric field. With the increase of the concentration of sol–gel precursor in the electrospinning solution, the diameter of nanoparticles in resulting fibers decreased from 60 to 13 nm. This composite nanomaterial will have potential applications in photoluminescent (PL), electroluminescent (EL) and non-linear optical devices, flat panel displays, photocathodes for solar and so on.
