She said, graphene is the thinnest, lightest, strongest (stronger than high-strength steel), extremely flexible and almost totally transparent material. It has many attractive / intrinsic properties like mechanical, thermal, electrical, acoustical etc. It has high electron mobility at room temperature (250000 cm2/Vs) exceptional thermal conductivity (5000 Wm−1·K−1) and superior mechanical properties with Young's modulus of 1 TPa. VSM analysis is the best tool to differentiate graphene from diamagnetic material graphite.
She further added that applications of graphene are myriad and some obvious including rapid-charging lithium-ion batteries, super-capacitors, printable electronics, foldable LED touch-screens, improved DNA sequencers, corrosion-resistant coatings, improved cement / concrete materials, a replacement for Kevlar, terahertz wave generators for extremely fast wireless communication, more efficient light-bulbs etc. Incorporation of small quantity of graphene fillers into polymer creates novel nano-composites with improved structural and functional properties (like electrical, physical, mechanical, and barrier properties of polymer composites at extremely low loadings) for utilisations in applications ranging from transportation, biomedical systems, sensors, electrodes for solar cells and electromagnetic interference.
