MANUFACTURING METHOD FOR GRAPHENE HOLLOW PARTICLE AND GRAPHENE HOLLOW PARTICLE USING THE SAME

摘要

Graphene hollow particles according to the present invention are able to be manufactured by comprising: a) a step of manufacturing a dispersion including a colloid solution having a graphene oxide solution and polymer particles; b) a step of spraying the dispersion in droplets; c) a step of performing pyrolysis by transferring the droplets to a pipe-shaped heating furnace; and d) a step of collecting pyrolyzed hollow particles. The graphene hollow particles according to the present invention are able to be mass-produced since graphene capsules are simply and rapidly produced by a single process and are widely used in a biosensor, a biocatalyst, an adsorbent for organic materials, a semiconductor electrode, a fuel cell, a hydrogen storage material and the like by excellent mechanical, electrical and thermal properties of graphene. Additionally, the present invention is able to control the hollow size of graphene composites produced according to the sprayed particle size of polymers with a method of depositing graphene on surfaces of polymers included in aerosol droplets and removing the polymers through pyrolysis.
