▎ 摘　　要

NOVELTY - The method involves preparing graphene oxide powder, and preparing cellulose solution. 5-10% gelatin solution is prepared. Graphene oxide powder is added into the gelatin solution. Ultrasonic treatment is carried out at 40-50 degree Cat 200-400w for 10-60 mm. A two-component crosslinking curing agent is prepared. The gelatin solution and the two-component crosslinking curing agent are gradually dripped into the cellulose solution. The cellulose solution is kept in an ice-water bath. The cellulose solution is stirred for 40-60 mm at 200-500 r/min. The surface with distilled water is washed after the solution is solidified to remove excessive crosslinking curing agent. The surface with distilled water is naturally dried in the shade. USE - Method for preparing a graphene/cellulose hydrogel with rapid heat dissipation and fever cooling patch (claimed) to treat a children with fever. ADVANTAGE - The method enables arranging graphene in the hydrogel, so that heat conduction capability can be greatly increased, the heat dissipation is rapid and efficiency of heat conduction paste can be better indicated by adding a temperature change indicator. The reaction preparation conditions are mild and suitable for large-scale production. The method utilizes microcapsule temperature change pigment to better indicate whether cooling patch is invalid. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a cooling patch.
