Researchers develop a new method for water-based, layer-selective exfoliation of few-layer graphene

Researchers at Korea-based Edmayim Corp., a materials R&D company specializing in scalable advanced carbon technologies, have reported a practical and scalable graphene exfoliation method based on interlayer expansion followed by controlled centrifugation, enabling reproducible fractionation of few-layer graphene. The process uses a water-based, environmentally benign exfoliation pathway without chemical oxidants.
