▎ 摘　　要

NOVELTY - Method for preparing reduced graphene oxide fluoroprotein heat extinguishing agent comprises (i) adding gelatin into graphene oxide solution in a mass ratio of 1:(10-100), and fully stirring and ultrasonically processing to obtain solution, (ii) adding reducing agent into the obtained solution and boiling to form a reduced graphene oxide sol coated with denatured protein, and (iii) adding fluorine-containing surfactant into the solution obtained in the step (ii) and fully stirring, where the fluorine-containing surfactant is an ionic fluorine surfactant and/or nonionic fluorine surfactant. USE - The method is useful for preparing reduced graphene oxide fluoroprotein heat extinguishing agent. ADVANTAGE - The method stabilizes the reduced graphene oxide and avoids sedimentation. The agent has same stability as general fluoroprotein heat extinguishing agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for reduced graphene oxide fluoroprotein heat extinguishing agent prepared by the above mentioned method.
