Carbon Nanoscrolls Produced from Acceptor-Type Graphite Intercalation Compounds

A low-temperature wet chemistry technique for producing carbon nanoscrolls is described. The technique is based on the use of readily available acceptor-type graphite intercalation compounds. The initial graphite intercalation compound is first exfoliated to produce a suspension of graphene monolayers in ethanol which is subsequently sonicated yielding a suspension of carbon nanoscrolls. The technique does not require heating and the use of inert atmosphere thus providing an improvement compared to the previously reported methods.
