TLDR
In this paper, high quality graphene sheets have been prepared by a facile liquid phase exfoliation of worm-like graphite (WEG), and this approach combining with advances in large scale industry manufacturing of WEG could potentially lead to the development of new and more effective graphene products.Abstract:
