Abstract

Graphene nanoplatelets (GnP) can be made into a thin 'paper' through vacuum filtration of GnP suspension. Electrodes were fabricated from the compressed GnP paper and then by coating the surface with epoxy. The electrostatic actuator was constructed from two parallel-aligned composite papers fixed at the anode and a cathode connected to ground. The two composite papers would then separate when a voltage was applied. The GnP paper was also modified to increase surface area by introducing porosity or adding ∼10 wt% C750 (GnP with diameter less than 1 μm); or changing the relative permittivity by adding barium titanate particles; or combining these two effects by adding CNCs. Overall the output work could be significantly improved to over 400%.
