MANUFACTURING METHOD FOR GRAPHEME-BASED NANOCOMPOSITE VIA SEQUENTIAL ADSORPTION METHOD

摘要

The present invention relates to a manufacturing method of transition metals (M1M2)/graphene nanocomposite material, comprising a step of mixing a precursor solution of the transition metal (M1) and a precursor solution of the transition metal (M2) including phosphate with a surfactant solution in which graphene or graphene oxide is dispersed wherein the M1 and the M2 are the same or lithium, manganese, cobalt, nickel, iron, titanium or vanadium. In the method for synthesizing nanocomposite material based on graphene, a consecutive adsorption method is introduced and accordingly induces electrostactic attraction between graphene or graphene oxide, metal positive ions and negative ions, leading to a synthesis method of nanocomposite material based on various metal oxides like lithium metal phosphate and nanocomposite-made graphene.
