An Efficient Molten Salt Method to Fabricate Light-colored Conductive Whiskers for Fibers

One-dimensional titanium dioxide (TiO 2 ) whiskers with controllable aspect ratios were synthesized by molten salt method adopting anatase TiO 2 nanoparticles as precursor, sodium chloride (NaCl) and dibasic sodium phosphate (Na 2 HPO 4 ) as medium. The particle size of TiO 2 nanoparticles and ratio of precursor and medium that can help to generate high aspect ratio TiO 2 whiskers were studied and selected. Light-colored antimony-doped tin oxide @ titanium dioxide (ATO@TiO 2 ) conductive whiskers were prepared by coating ATO on TiO 2 whiskers through coprecipitation then. Finally, the ATO@TiO 2 light-colored conductive whiskers were dispersed in polyacrylonitrile (PAN) to fabricate light-colored conductive fibers. The experimental results show that the ATO@TiO 2 whiskers exhibits ideal whiteness and conductivity with 65.5 Wb and 106 Ω·cm, respectively, and the resistivity of conductive fibers was 6.07×10 6 Ω·cm with 15wt% whisker content.
