阶层式多孔二氧化钛的制备及其结构与性能研究

The Preparation,Structure and Performance of Hierarchically Porous TiO_2

针对阶层式多孔二氧化钛有效构筑的难题,采用静电纺丝与高分子共混体系相分离相结合的策略,基于高分子与二氧化钛前驱体的相互作用,成功制备了具有微米/纳米两个尺度孔结构的二氧化钛无纺布,所得材料具有良好的力学和光催化性能.

The preparation of hierarchically porous TiO2 remains as a great challenge. In this work, a new strategy for this purpose is developed by the combination of electrospinning and phase separation in polymer blend based on the interaction between polymer and the precursor of TiO2. The resultant TiO2 fabrics exhibit pore size distribution in micro and nano scales as well as good mechanical and photo catalysis performances.
