In this study, cotton fabrics were reported to be typically functionalized by loading silver nanowires (AgNW) on the surface of the polydopamine modified cotton fabric. Firstly, AgNW were prepared by a polyol method and then a polydopamine-modified cotton fabric was prepared by being immersed in AgNW dispersion by the dip-coating method. The resulting silver nanowire/polydopamine/cotton-based nanocomposites (APCN) has a surface specific resistance as low as 2.4 Ω and has good durability and flexibility. In addition, the electrothermal properties of APCN were investigated by applied voltage. The result showed that the composite material can reach 80 °C in a short time under the voltage of 1.8 V, and conform to the power balance model. The steady-state temperature of the composite material is closely related to the voltage, and has a quadratic relationship with the voltage and expresses linear relation with the electric power.
