Embodiment 1

[0055] (1) Preparation of graphene bubbles: first prepare graphene oxide (GO) sheets by Hummers method, then mix graphene oxide (GO) sheets with nickel chloride, stir magnetically at a temperature of 70°C for 2 hours, and then add hydrazine hydrate After reduction, 0.5 mol / L sodium hydroxide (NaOH) was added, reacted for 2 hours, and washed with ethanol and deionized water. Then by chemical vapor deposition, methane and hydrogen are introduced into the tube furnace at 700°C to coat the graphene on the surface of the nickel balls, and at the same time, graphene oxide (GO) sheets are reduced to graphene at high temperature. The nickel is etched with hydrochloric acid, and finally the graphene bubble hollow sphere material is obtained.

Abstract

The invention provides high-thermal-conductivity graphene foam modified bamboo fiber yarn and a preparation method thereof. The method comprises the following steps that (1) graphene foam and a polymer are mixed evenly to prepare a composite solution of the graphene foam and the polymer, wherein the graphene foam is a graphene hollow sphere, and the polymer is selected from one or more of polyvinyl alcohol, polycaprolactone, polyacrylonitrile and polystyrene; (2) the composite solution obtained in the step (1) is made into nano-fibers; and (3) bamboo fibers and the nano-fibers obtained in thestep (2) are blended, and thus the high-thermal-conductivity graphene foam modified bamboo fiber yarn is obtained. By being tested, the high-thermal-conductivity graphene foam modified bamboo fiber yarn provided by the invention has an outstanding bacteria resistance and inhibition effect; bacteria can hardly survive on the yarn, even after hundreds of washing tests, the bacteria inhibition effectis still higher than 90%, and the function fastness is outstanding.

Description

technical field [0001] The invention relates to the field of textile materials, in particular, the invention relates to a high thermal conductivity graphene foam modified bamboo fiber yarn and a preparation method thereof. Background technique [0002] Functional textiles have always been one of the hot research fields in the textile industry. It is difficult for traditional materials to balance functionality and comfort at the same time. With the improvement of living standards, people have more and more demands for personalization, such as moisture absorption, antibacterial, heat conduction and heat insulation, etc. [0003] Generally, graphene is stripped from graphite, and the cost is relatively high. Graphene described in this patent is obtained by pyrolysis of biomass carbon-containing materials. Due to the wide range of sources of biomass materials and low price, the cost of graphene is greatly reduced. , which also provides feasibility for its wide application in va...
