Ever since the isolation of graphene was first achieved in 2004, there has been an explosion in graphene-related research and development, with hundreds of business opportunists producing graphene to capitalise on this rapidly expanding industry. However, a new study by researchers from the National University of Singapore (NUS) has uncovered a major problem – a lack of production standards has led to many cases of poor quality graphene from suppliers. Such practices can impede the progress of research that depend fundamentally on the use of high-quality graphene.
