In this work, one-dimensional TiO2 whiskers were first synthesized via a green and efficient approach, namely a microwave-assisted heating method. Then, after chemical co-deposition and calcination, an antimony-doped tin oxide (ATO) layer was deposited on the surface of the TiO2 whiskers. This resulted in light-colored conductive ATO@TiO2 whiskers with a core–shell structure. The resistivity and whiteness value of the one-dimensional ATO@TiO2 whiskers prepared under the optimal experimental parameters were 211 and 85.81 Ω cm, respectively. Moreover, a one-dimensional composite fiber and a two-dimensional composite film with resistivities of ~ 100 and ~ 10 kΩ cm, respectively, were obtained when 20 vol% ATO@TiO2 whiskers were used as a conductive filler. In contrast to the strategies used for traditional conductive materials, which are expensive or dark in color, this fabrication strategy represents a facile low-cost route for manufacturing fillers that can overcome the constraints of color and cost and extend the applicability of conductive fillers.
