title: Fast Production of High-Quality Graphene via Sequential Liquid Exfoliation.
abstract: A novel and practical approach of exfoliating graphite into graphene uses a sequence of flow and sonication on graphite suspensions. Graphite sediment after intense mixing is found to be altered, graphite having curled-up edges, which increases its sensitivity to ultrasound. Quadrupled graphene yield is achieved through introducing flow pretreatment.
