摘要

One-dimensional titanium dioxide (TiO2) whiskers with controllable aspect ratios were synthesized by molten salt method adopting anatase TiO2 nanoparticles as precursor, sodium chloride (NaCl) and dibasic sodium phosphate (Na2HPO4) as medium. The particle size of TiO2 nanoparticles and ratio of precursor and medium that can help to generate high aspect ratio TiO2 whiskers were studied and selected. Light-colored antimony-doped tin oxide @ titanium dioxide (ATO@TiO2) conductive whiskers were prepared by coating ATO on TiO2 whiskers through coprecipitation then. Finally, the ATO@TiO2 light-colored conductive whiskers were dispersed in polyacrylonitrile (PAN) to fabricate light-colored conductive fibers. The experimental results show that the ATO@TiO2 whiskers exhibits ideal whiteness and conductivity with 65.5 Wb and 106 Ω·cm, respectively, and the resistivity of conductive fibers was 6.07×106 Ω·cm with 15wt% whisker content.
