Precipitation method to prepare conductive F-doped SnO 2 -coated rutile TiO 2 whisker and its application in coating

In this work, K 2 Ti 4 O 9 whiskers are prepared by adding a certain amount of NaCl as the whisker reaction slow-release agent. Rutile TiO 2 whiskers are obtained by ion exchange and microwave sintering method with K 2 Ti 4 O 9 whiskers as templates. The surface morphology and crystal structure of K 2 Ti 4 O 9 whiskers are analyzed and characterized by scanning electron microscope (SEM), X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), and energy-dispersive X-ray spectroscopy (EDS). One-dimensional conductive whiskers of fluorine-doped tin dioxide-coated rutile titanium dioxide (FTO@TiO 2 ) were prepared by the hydrothermal chemical combined precipitation method. Under the optimized conditions, the resistivity of the conductive whiskers was 0.625 kΩ, and the Hunter whiteness is 80.3. Additionally, FTO@TiO 2 conductive nanomaterials were dispersed into acrylic polymer emulsion (APE) to make antistatic slurry and coat it on the surface of the polyester fabric. After the antistatic coating has dried, FTO@TiO 2 whiskers are located in the coating mold; FTO@TiO 2 whiskers bridge each other to form a current path, so that the fabric has antistatic properties. Under the best experimental parameters, the FTO@TiO 2 whiskers possessed excellent electrical conductivity, and the surface resistance of the coated fabric can reach 10 6 Ω, and it presented certain antistatic properties as well.
