Problems solved by technology

[0006] The technical problem to be solved by the present invention is that in the prior art, pure MXene is used as the electrode layer. Due to poor film formation, there will be many cracks in the middle, which will directly affect the conductivity of the electrode layer and reduce the driving performance of the driver.

Abstract

The invention discloses a method for preparing an MXene / CNT ion-type electrochemical driver, and relates to the technical field of materials science. The invention includes the following steps: (1) preparing an MXene / CNT electrode film; (2) preparing a polymer layer: combining thermoplastic polyurethane and ion The liquid is placed in an organic solvent 2, heated and stirred to a transparent liquid, and the transparent liquid is dropped on the substrate and dried to form a polymer layer; (3) the MXene / CNT electrode film, polymer layer, MXene / CNT electrode The membranes are stacked sequentially. The invention has the beneficial effects of reducing the response time of the driver and improving the driving performance of the driver, and the maximum deformation displacement of the manufactured driver is 24mm at low frequency. Secondly, it can also improve the interlayer electronic conduction and mechanical stability of MXene, and increase the film-forming property of MXene.

Description

technical field [0001] The invention relates to the technical field of materials science, in particular to a preparation method of an MXene / CNT ion-type electrochemical driver, the prepared driver and its application. Background technique [0002] Ionic electrochemical actuator is a kind of bionic artificial muscle material. Because of its light weight, softness, low actuation voltage and large deformation capacity, it can produce large displacement deformation and strain under low driving voltage. It can be used as A new type of actuator is well suited for the development of biomimetic artificial muscles. [0003] Ionic electrochemical actuators are generally composed of electrode layers and polymer electrolyte intermediate layers by hot pressing. MXene(Ti 3 C 2 T x ) have been applied to electrochemical actuators because of their high volumetric capacitance and fast electron transport rate. [0004] MXene is an emerging two-dimensional material composed of transition m...
