Sustainable technologies for the direct and bulk conversion of waste biomass into graphene
Despite being considered as the ‘wonder material’, graphene’s use is limited by the quantity during its production.
Background
Usually graphene is produced by annealing silicon carbide substrates, growing on metal substrates, chemical vapour deposition, exfoliation of graphene oxides, etc. However, these methods give low yield of graphene that might lack spatial uniformity over larger length and possesses defects. Moreover, these methods include increased solution processing and a large number of steps that increase the cost significantly.
Aim & Objectives
The objective is to catalytically convert waste biomass into graphitic carbon through pyrolysis and then into bulk graphene through mechanical exfoliation without creating an intermediary amorphous carbon. Additionally, the fire resistance and mechanical properties of composites having this graphene will be determined.
