Abstract

See full text

A method of exfoliating graphite into graphene uses a sequence of flow and sonication on graphite suspensions. Graphite particles after intense mixing/grinding in a liquid are found to be altered, graphite having curled-up edges, which increases its sensitivity to ultrasound. Quadrupled graphene yield is achieved through introducing chaotic flow pretreatment.
