Graphene has excellent electromagnetic, mechanical, thermal, and optical properties and has been widely applied in materials science, biomedicine, physics, energy storage, chemistry, and textile fields all over the world. In this paper, graphene conductive fabrics were prepared by the impregnation method, and ascorbic acid was used as a reducing agent. Ammonia-cotton blended fabric was used as the base material. Results indicated that graphene had been successfully covered on fabrics according to XRD and SEM analysis. The optimum technological parameters for preparing graphene conductive fabrics were: impregnation five times, reduction temperature at 95 °C, the ascorbic acid concentration of 0.06 mol/L, and the reduction time was 40 min. A corrosion study indicated that rGO fabrics could be partly corroded in 3 wt.% NaCl solution, leading to a decrease in resistivity. However, the conductive ability of rGO fabric changed little with time due to the good stability of rGO.
