Abstract

The invention discloses a multifunctional graphene modified non-woven fabric and a preparation method thereof. The multifunctional graphene modified non-woven fabric is obtained by blending nano-carbon blacks having specific DBP values with reduced graphene oxide at a specific ratio, blending the mixture with polypropylene, and conducting melt-spraying. The nano-carbon blacks with different DBP values are distributed in different regions of the surface of the reduced graphene oxide to form a unique nano-composite structure, so that the non-woven fabric exhibits excellent electrical conductivity., and after the addition of the polypropylene, the antistatic property of the non-woven fabric can be effectively improved. At the same time, through the addition of graphene, the far-infrared emission, anti-ultraviolet, antibacterial and anti-mite effects of the polypropylene non-woven fabric can also be significantly improved, and thus the polypropylene non-woven fabric can be applied in the fields of home textiles, carpets, garments, masks, medical protective gears and the like.

Description

technical field [0001] The invention belongs to the field of non-woven fabrics, and in particular relates to a multifunctional graphene-modified non-woven fabric and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional honeycomb nanomaterial composed of carbon atoms that was first discovered in 2004. In the graphene plane, the carbon atoms are all sp2 hybridized, forming a six-membered ring bond in the plane, and forming a large π bond that runs through the entire layer in the direction perpendicular to the layer plane, thus providing an excellent electron transfer condition. The researchers found that the carrier mobility of graphene at room temperature reached 15000 cm 2 / (V·s), which is more than twice that of indium telluride, the material with the highest carrier mobility, and the carrier mobility changes little with temperature, so it has a significant role in the fields of conductive materials and electronic materials. applicati...
