Carbon nanotube, CNT, is a one dimensional sp2 allotrope of carbon with cylindrical nanostructure and high aspect ratio (length in microns and diameter in the nanometer order). They could exist as either single-walled nanotube (SWNT) or Multi-walled nanotube (MWNT), depending on the number of layer(s) present. CNTs drawn into fibres shows outstanding mechanical and electrical properties which give them edge in applications such as composites, electrodes, mechanical actuators, power cable ...
Graphene has attracted world-wide attention due to its intriguing set of properties. However, the production of graphene on the bulk scale remains a significant challenge which is limiting its uptake in applications, particularly composites. The exfoliation of graphene in solvents using ultrasonic energy is the most promising approach to-date for the large scale production of graphene flakes. The process relies on a good interaction between the graphene and the solvent used. This interac...
