Graphene/carbon nanotube-based conductive materials

This project is basically an investigation of graphene and carbon nanotube (CNT) based material’s electrical properties. In its first part, graphene (G) and graphene oxide (GO)/carbon nanotubes (CNTs) hybrid films were successfully fabricated as highperformance electrode materials for an energy storage application using a simple water solution casting method and with an assistance of strong ultra-sonication. This was done with different contents of G, GO, single-wall CNT (SWCNT), multi-wall CNT (MWCNT) and multi-wall CNT with a hydroxyl group (MWCNT-OH). The films with MWCNTs showed well interconnected layered structures at the nanoscale range where GO worked as support insulated plates for the CNTs. [Continues.]
