▎ 摘　　要

NOVELTY - Flexible electric heating fabric comprises a fabric substrate and a conductive complex layer set on the surface of the fabric substrate. The conductive complex layer including a first conductive layer, a second conductive layer and a third conductive layer set sequentially cascade. The first conductive layer is loaded on the surface of the fabric substrate. The first conductive layer is a two-dimensional MXene coating. The second conductive layer is a one-dimensional metal nanowire coating. The third conductive layer is a graphene layer. The conductivity δ1of the first conductive layer is 1-4 s/m. The conductivity δ2of the second conductive layer is 3- 16 s/m and the conductivity δ3 of the third conductive layer is 10-50 s/m and δ1:δ2:δ3is 3:5:10. USE - The fabric is useful in electronic industry. ADVANTAGE - The fabric: is convenient to wear and has electromagnetic shielding, conductive function, electric heating cold-resisting effect in extreme environment and good application prospect.
