摘要：In this work, one-dimensional conductive TiO₂ whiskers coated with antimony-doped tin oxide (ATO@TiO₂) were prepared with a method of hydrothermal coprecipitation. Specially, sodium hexametaphosphate (SHMP) was used as an interfacial reactor to form sufficient active groups on the surface of TiO₂ whiskers, which not only increased the reaction sites, but also formed the electric double-layer structure to promote the dispersion of TiO₂ whiskers in aqueous solution. Additionally, four kinds of ATO@TiO₂ nanomaterials with different appearances were introduced into waterborne polyurethane (WPU) emulsion to prepare the conductive paint for the surface coating of polyester fabrics. During the process of curing reaction, ATO@TiO₂ whiskers are located in the coating mold to organize a conductive network in the form of a rod-to-rod connection. Compared with particle-type ATO@TiO₂, the percolation threshold was drastically decreased from 45 to 7.5 wt%, meanwhile, this conductive paint shows excellent covering performance and the whiteness is up to 83.
