Abstract

The invention discloses a multifunctional graphene-modified non-woven fabric and a preparation method thereof. By selecting nano-carbon black with a specific DBP value to compound with reduced graphene oxide in a specific ratio, blending with polypropylene, and melt-blowing after getting. Nano-carbon blacks with different DBP values ​​are distributed in different regions on the surface of reduced graphene oxide, forming a unique nano-composite structure, showing excellent electrical conductivity, and adding polypropylene can effectively improve the antistatic properties of non-woven fabrics. At the same time, the addition of graphene can also significantly improve the far-infrared emission, anti-ultraviolet, antibacterial and mite-removing effects of polypropylene non-woven fabrics, which can be used in home textiles, carpets, clothing, masks, medical protective gear and other fields.

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...
