Abstract Graphene has attracted much attention due to its possible applications in various fields. However, graphene tends to aggregate and restack easily due to strong van der Waals attraction. Thus novel method for the rapid and continuous synthesis of aggregation-resistant graphene was suggested and achieved by morphing graphene sheet into crumpled paper ball-like graphene via an aerosol-assisted capillary compression process. Here we report new method for the preparation of the crumpled graphene particles with enhanced properties via microwave plasma-assisted capillary compression process. Aerosol droplets containing graphene oxide (GO) sheets were evaporated and reduced by passing through a tube reactor equipped with a microwave plasma system, resulting in crumpled and chemically reduced graphene (a.k.a., reduced GO, r-GO) particles. The crumpled morphology was observed by FE-SEM and the chemical reduction of GO was verified by XPS result. Superior specific surface area (409 m$^2/g) was measured by nitrogen absorption. The higher energy by microwave plasma enhanced the properties of crumpled graphene particles.
