新型有机-无机杂化纳米纤维，即聚乙烯醇（PVA）-乳酸钛（TL）杂化纳米纤维，采用水作为溶剂通过静电纺丝形成。通过在空气中煅烧混合纳米纤维获得锐钛矿型二氧化钛纳米纤维。 PVA-TL杂化纳米纤维的纤维直径为200-350 nm，TiO2纳米纤维的纤维直径为PVA-TL杂化纳米纤维的70-80%。 500℃煅烧5h的TiO2纳米纤维的比表面积和平均孔径分别为21.0m2/g和7.4nm。还研究了使用 TiO2 纳米纤维光催化分解亚甲基蓝。 © 2007 Wiley periodicals, Inc. J Appl Polym Sci 104: 1232–1235, 2007
New organic-inorganic hybrid nanofibers, poly(vinyl alcohol) (PVA)-titanium lactate (TL) hybrid nanofibers, were formed by electrospinning employing water as a solvent. Anatase-type TiO2 nanofibers were obtained by calcination of the hybrid nanofibers in air. The fiber diameters of the PVA-TL hybrid nanofibers was 200–350 nm, and the fiber diameter of the TiO2 nanofibers was 70–80% of that of the PVA-TL hybrid nanofibers. The specific surface area and average pore diameter of the TiO2 nanofiber calcined at 500°C for 5 h were 21.0 m2/g and 7.4 nm, respectively. The photocatalytic decomposition of methylene blue using the TiO2 nanofibers was also investigated. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 104: 1232–1235, 2007
