▎ 摘　　要

NOVELTY - Expansion graphite is expanded to obtain graphene worm. The obtained graphene worm is thermally processed after crushing for two or more times, and cut while homogenizing through high pressure homogenizer in presence of a solvent mixture. The resultant material is subjected to ultrasonic processing to obtain mixed dispersion of graphene and graphite nano plate. USE - Manufacture of mixed dispersion of graphene and graphite nano plate. ADVANTAGE - The method efficiently and economically provides mixed dispersion of graphene and graphite nano plate having high quality, by simple process with reduced consumption of organic solvent without affecting environment in short period of time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of mixed powder of graphene and graphite nano plate.
