Abstract We describe our efforts to scale up the production of graphene powders produced by the detonation synthesis method. Historically, the detonation synthesis method began with a tedious gas fill-up phase, and ended with a long clean-out phase. We added electronic flow-meters to speed up the fill-up phase, and tested how fill-up time impacts the quality and yield of the final sample. We also ran tests on the chamber size to prove that the same sample quality and fractional yield was obtained. Finally, to improve the clean-out phase, a system to withdraw the sample after detonation was developed and tested. With all of these parameters, we push to achieve production of 1kg of detonation graphene per day.
