Abstract

The invention discloses a nano particle agglomeration type nano porous electrochemical driver and a preparation method and testing method thereof. The driver comprises a deposition substrate of a flexible conductor material and a driving film deposited on the deposition substrate. According to the preparation method, high-energy laser beam bombardment is utilized to realize the transformation of atarget material from a solid state to an plasma state to a solid state, and thus the nano particle agglomeration type nano porous driving film can be formed on different substrates. The nano porous electrochemical driver with controllable particle size can be obtained by adjusting and controlling preparation conditions such as target base spacing, substrate rotating speed and deposition temperature. The defect that a traditional electrochemical driver cannot achieve both the response rate and the deformation capability at the same time is overcome; and by shortening the ion embedding path andimproving the ion adsorption capacity, the driving speed and the deformation amplitude value are synchronously improved. The driver has the advantages of high response speed, high driving amplitude,high object carrying driving capability, simple process and low cost, and the application of the electrochemical driver in the fields of small medical instruments, micro-nano electromechanical systemsand the like can be promoted.

Description

technical field [0001] The invention relates to the technical field of electrochemical drive, in particular to a high-performance nanoparticle agglomeration type nanoporous electrochemical drive and its preparation and testing methods. Background technique [0002] Electrochemical drives generate mechanical energy through chemical reactions at low voltages. Compared with other types of drivers, electrochemical drivers have lower driving voltage and higher energy output, so they have broad application prospects in artificial muscles, intelligent robots, and micro-nano electromechanical systems. For electrochemical actuators, response rate and deformability are two crucial but opposing parameters. More specifically, low-modulus gel or conductive polymer-based electrochemical actuators have excellent deformation capabilities, but their response rates are extremely slow; in comparison, carbon nanomaterial electrochemical actuators have a faster response rate. , but its deforma...
