Graphene was prepared via microwave assisted intercalation-exfoliation of graphite by using ammonia as intercalation agent. The effects of ammonia on graphene preparation and its intercalation mechanism were investigated. It was found that ammonia can greatly improve the exfoliation effect of graphene in the way of entering into the interlayer between graphite and forming C˭N bond. The quality of...
This work presents a facile and novel method to fabricate graphene via microwave-assisted NH3 molecule intercalation-exfoliation of graphite. Specifically, dibasic ester (DBE) was chosen as the solvent due to its suitable surface energy and nontoxicity. The microstructure of as-prepared samples was characterized by Transmission electron microscopy, Raman spectrometry, and Field emission scanning electron...
