[0020] A preparation method of medical graphene conductive gel, the steps of the preparation method are:
[0021] A. Disperse the graphene nanosheets in water, stir and disperse, and further disperse through an ultra-high-speed nano ball mill to obtain a highly dispersed graphene aqueous phase dispersion;
[0022] B. Add deionized water into the reaction kettle, and raise the temperature to 80-90°C, add the graphene nanosheet aqueous phase dispersion and synthetic hydrogel monomer into the reaction kettle in turn, and continue to stir at 300-500rpm for 30 -60 minutes;
[0023] C. Add a cross-linking agent to the mixed solution obtained in step B, stir while adding, and continue stirring for 2-4 hours after the addition is completed. After the stirring is completed, cool at room temperature and inject into the mold to obtain a graphene conductive gel.
