Abstract

The invention discloses a self-cleaning graphene carbon fiber non-woven fabric and a preparation method thereof. The self-cleaning graphene carbon fiber non-woven fabric comprises a self-cleaning coating and a graphene carbon fiber base fabric; the self-cleaning coating is prepared from the following raw material substances of nano silicon oxide, graphene powder, methyltrimethoxysilane, methanol and water; and the graphene carbon fiber base cloth is prepared from the following raw material of graphene oxide, carbon fibers and nano-silver fibers. According to the self-cleaning graphene carbon fiber non-woven fabric, the self-cleaning coating is sprayed on the graphene carbon fiber base cloth, so that the hydrophobicity of the surface of the graphene carbon fiber non-woven fabric is improved, the surface of the graphene carbon fiber non-woven fabric has a large contact angle, the self-cleaning performance is good, and the surface of the non-woven fabric can be kept clean and free of pollution for a long time.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a self-cleaning graphene carbon fiber nonwoven fabric and a preparation method thereof. Background technique [0002] The self-cleaning surface with "lotus leaf effect" has good superhydrophobicity and strong anti-pollution ability. Self-cleaning surfaces have the advantages of water saving, energy saving, and environmental protection, and have attracted more and more attention. [0003] Graphene fiber non-woven fabric is a new type of non-woven fabric made of graphene fibers. Due to the fusion of graphene fibers at the overlapping joints and the excellent characteristics of graphene, it has excellent electrical and thermal conductivity. Flexible fabric electrodes are widely used in the field of energy storage devices such as capacitors and batteries. [0004] At present, the existing graphene fiber non-woven fabrics have good flexibility and high electrical conductivi...
