NOVELTY - Preparing glycerol graphene quantum dot nano-fluid involves mixing the glycerol and the carbon-containing precursor at room temperature, stirring for 0.5-1 hours at room temperature, dispersing carbon-containing precursor uniformly in the glycerol, moving the solution obtained to the reaction kettle with polytetrafluoroethylene lining, heating at 100-200 degreesC with heating device for 4-6 hours, cooling to room temperature and taking out; putting the solution obtained into an ultrasonic dispersion device, ultrasonically dispersing for 1-3 hours at 30 degrees Celsius to obtain graphene quantum dot nano-fluid with glycerol as base liquid. USE - Method for preparing glycerol graphene quantum dot nano fluid as base liquid. ADVANTAGE - The method solves the problem of high viscosity of the glycerol nano fluid and bad heat conductivity.
