Graphense is a two-dimensional monolayer of carbon atoms packed into a honeycomb lattice that has extraordinary electronic, thermal and mechanical properties. In this study, we prepared electro-conductive graphene/polymer hybrid spheres through charge-charge interaction between ionic polymer sphere of host and charged reduced graphene oxide of guest. To obtain charged reduced graphene oxide, the chemical exfoliation - reduction of expandable graphite was employed, and ionic polymer spheres of various scales were prepared via soup-free emulsion polymerization. Furthermore, preparation of hollow graphene balls through calcination of graphene/polymer hybrid spheres were performed for the purpose to obtain transparent conductive materials. |
