Graphene growth kinetics for CO2 laser carbonization of polyimide
PhD student Ratul Biswas has published his second paper in Elsevier Materials Letters on optimising laser write conditions for laser induced Graphene created from inscription of polyimide. Arrhenius Growth of Graphene crystallite from Polyimide was studied and activation energy of growth was calculated for CO2 laser carbonization. This study will help to control average graphene crystallite size by proper control of laser fluence and scan speed. Thanks to the NCLA – National Centre for Laser Applications team and DCU team for their support! #Graphene#Laser#micromachining
The figure shows that ID/IG was found to increase with increasing scan-speed, and that the crystallite growth of Graphene from Polyimide follows the Arrhenius equation.
