摘要: Flexible actuators are widely in demand for many real-life applications. Considering that existing based on polymers, low-dimensional materials and pore-rich mostly limited by slow response rate, high driving voltage poor stability, we report here a novel metal flexible actuator which is fabricated simply through partial oxidation nano-function of copper foil with the assistance reduced graphene oxide. The obtained asymmetric metallic (electric-)thermally driven exhibits fast rate (∼2 s) large curvature (2.4 cm−1) under low (∼1 V) sustainable operation up to ∼50 000 cycles. can also be triggered infrared irradiation direct-heating various conditions including air, water, vacuum.
