A Chemists Method for Making Pure Clean Graphene
Even before Geim and Novoselov’s Nobel Prize in Physics 2010 "for groundbreaking experiments regarding the two-dimensional material graphene". the interest of physicists in graphene was enormous compared to that of chemists. This probably results from the absence of a well-established large scale method to produce graphene. Therefore, the most important role chemists can play is the establishment of an inexpensive and simple wet-chemical method for making graphene. Herein, we describe an intercalation method to make clean graphene that has good electrical properties. The new method is based on an earlier procedure to make expanded graphite. Our method leads to the production of graphene.
