A Flexible Metallic Actuator Using Reduced Graphene Oxide as a Multifunctional Component

Abstract

Flexible actuators are widely demanded in many real-life applications. Considering that existing actuators based on polymers, low-dimensional materials and pore-rich materials are mostly limited by slow response rate, high driven voltage and poor stability, we report here a novel metal based flexible actuator which is fabricated simply through partially oxidation and nano-function of copper foil with the assistance of reduced graphene oxide. The obtained asymmetric metallic actuator is (electric-)thermal-driven and exhibits fast response rate (~2 s) and large curvature (2.4 cm-1) under a low voltage (~1 V) with sustainable operation up to ~50000 cycles. The actuator can also be triggered by infrared irradiation and direct-heating under various conditions including air, water, and vacuum.
