▎ 摘  要

NOVELTY - Preparing fast radiating graphene/cellulose hydrogel involves preparing graphene oxide powder, preparing cellulose solution, configuring 5-10 wt.% gelatin solution. The graphene oxide powder is added to the gelatin solution, ultrasound at 200-400 w for 10-60 minutes, under 20-30 degrees C. The double-component cross-linking curing agent is configured. The gelatin solution and the two-component crosslinking curing agent are gradually added dropwise into the cellulose solution. The cellulose solution is placed in ice water bath, and stirring 200-500 revolutions/minutes for 40-60 minutes. The distilled water is used to wash the surface washing excess cross-linking curing agent after the solution is solidified, and dried naturally. USE - Methof for preparing fast radiating graphene/cellulose hydrogel used for preparing cooling patch (claimed). ADVANTAGE - The method increases the heat conducting ability, radiates quickly, and can better indicate the efficiency of the heat conducting paste. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a cooling patch prepared by using the fast radiatinggraphene/cellulose hydrogel, which comprises a non-woven fabric layer, a hydrogel layer and an anti-sticking layer, where the hydrogel is coated on the nonwoven fabric layer, and the anti-sticking layer is PET film.
