    5. 내  용 :
I provide a brief update on experimental fracture mechanics of carbon nanotubes, specifically SWCNTs of known diameter and chirality. I then turn to discussing a new class of materials, the graphene-based materials. Our top-down approaches inspired physicists to study individual layers of graphite, but our current approach has been to convert graphite to graphite oxide (GO), generate colloidal suspensions of individual layers of GO (we call them ‘graphene oxide’) in water, and to use these individual layers 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, sheet morphology, and the electrical percolation and 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 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.
