NOVELTY - Preparing graphene microsphere by inverse emulsion method comprises using single-layer graphene oxide as raw material and includes (1) adjusting the pH of aqueous graphene oxide solution with a alkali compound to 9-11 in the aqueous system, (2) preparing oil phase composition system of liquid paraffin and carbon tetrachloride in a volume ratio of 6:1-15:1 and (3) adding surfactant to the oil phase composition system, adding the aqueous system in step (1) in a volume ratio 2:1-8:1, adding diamine composition, stirring and reacting at 40-100 degrees C for 3-8 hours to obtain graphene oxide microspheres. USE - The microsphere is useful for forming and maintaining high-strength porous spheres. ADVANTAGE - The microsphere: is assembled together by hydrogen bond or van der Waal force thus has a uniform and controllable size distribution; and has sufficient strength and porous structure.
