In this work, carbon fabric with uniform ZnO layers on the surface was successfully synthesized via a simple solvothermal method. The morphology, structural, chemical composition, optical, electrical and thermopower properties of ZnO-coated carbon fabrics was investigated. It was found that the volume of the zinc nitrate, hexamine and reaction time played important roles for the formation of uniform ZnO coatings on carbon fabric. The ultraviolet ray protection factor (UPF) of the fabric coated with ZnO could reach up to 201.7 but bare carbon fabric will be 28.62, meaning that high concentration hexamine could dramatically enhance the UV-shielding property. Furthermore, the ZnO coated carbon fabric also reported excellent electrical conductivity. The thermopower value of the ZnO coated carbon fabric could reach -0.054 µVK-1. It was expected that such conductive fabric has extensive application in wearable thermoelectric devices.
