Our top-down approaches [1,2] inspired physicists to study individual layers of graphite obtained by micromechanical exfoliation, and one of our current approaches has been to convert graphite to graphite oxide (GO), generate aqueous colloidal suspensions containing individual layers of GO (we call them ‘graphene oxide’), and to use these ‘graphene oxide sheets’ in a variety of ways. For example, we have embedded individual and reduced graphene oxide sheets in polymers such as polystyrene and evaluated their dispersion, morphology, and the electrical percolation and thus conductivity of the resulting composites. In parallel paths, we have: (i) undertaken studies of individual graphene oxide and reduced graphene oxide sheets, to elucidate their chemical, optical, and electrical properties, (ii) embedded graphene oxide sheets in glass by a sol-gel route and made electrically conductive and transparent glass coatings, and (iii) produced 'graphene oxide paper', a material with intriguing mechanical properties (iv) produced reduced graphene oxide powder with moderately high surface area and used this to study electrochemical double layer capacitance (v) made carbon-13 labeled graphite and thus carbon-13 labeled graphite oxide, and studied its detailed chemical structure with SS NMR. Finally, (vi) I will talk about recent work in our group on growing and characterizing graphene and few layer graphene films on metal substrates, and their transfer to other substrates for device fabrication and characterization. This survey talk about graphene and its chemical derivatives will present an overview of these various results. Support of our work by the NSF, ONR/NRL, NASA, and DARPA is appreciated. 1.
