Abstract

The invention discloses a double-stimulus-responding porous graphene driver which comprises a flexible polymer film. A graphene film is arranged on one side face of the polymer film and is of a multilayer structure, and micropores are formed between adjacent graphene layers; the driver is in bending deformation when receiving illumination or voltage stimulation. The invention further discloses a preparation method and application of the driver. The driver has the advantages that the driver can acquire double-stimulus response, so that environment adaptability of the driver is improved; bendingdeformation of the driver is caused jointly by expanding deformation of polymer when being heated and contracting deformation of graphene micropores, so that good mechanical performance is demonstrated, application range of the driver is widened, and using effect of the driver is improved. The driver can be used in the field of imitated-worm robots, manipulators, artificial joints and intelligentdrive.

Description

technical field [0001] The invention belongs to the field of flexible drivers and software devices, and in particular relates to a porous graphene driver responsive to dual stimulus sources, a preparation method and an application thereof. Background technique [0002] The drive device composed of flexible smart materials can respond specifically to external stimuli such as electricity, heat, chemistry, humidity, etc., and change its shape and size in a wide range. It has softness, flexibility, small size, light weight, fast deformation and environmental adaptation It has many advantages such as good performance, so it is widely used in bionic robots, artificial muscles, sensors, intelligent switches and other fields. However, the actuators currently studied can only be driven by one kind of stimulus, and cannot respond to multiple stimuli at the same time, resulting in low environmental adaptability; and the existing flexible actuators generally have the problem of poor mec...
