▎ 摘　　要

NOVELTY - A method for manufacturing graphite nanoplatelets by ultrasonic waves is disclosed. The method comprises the following steps: providing graphite oxide; performing a graphite oxide intercalation step to obtain urea nitrate intercalated graphite by an ultrasonic shock treatment and then filtering to graphite oxide, urea aqueous solution and nitric acid; and performing an expansion step to obtain graphite nanoplatelets by heating urea nitrate intercalated graphite at a predetermined temperature.
