In recent years,with the advent of electroactive polymer material(Electroactive polymers,EAP),artificial muscles that based on such materials has been widespread concerned.Higher production costs and low output power are the main production drawbacks of traditional IPMC artificial muscle,the use of silver electrode is not only easily lead to IPMC work in oxidation,fracture failure,but also the poor biocompatibility,So all the problems have limited its popularization.The purpose of this article is to provide a kind of biological compatibility materials to prepared a new process scheme for the new electric drives,thus the multi-walled carbon nanotubes(Multi-walled Carbon Nanotube,MCNT)is used for the preparation of non-metallic electrode,that was superior the silver electrode,the role of using ionic liquid instead of water in principle to solve the IPMC failure problem caused by water loss,and it is assembled into a more economical and practical artificial muscle.The factors affecting the performance of the electric actuator,the mass fraction of MCNT,the thickness of the electro-induced film and the electrode film,were studied,and the performance of the electric actuator was improved.The output force and the output displacement of the electric drive are tested and the mechanism of the actuator is analyzed.In this paper,on the basis of reading a large number of domestic and foreign literature,through the analysis and experimental textto research the preparation and assembly process of electrode membranes and electric drive determiningthe process of the electric drive and specific process parameters,by using the method of hot pressing to assemble it,getting the more optimum performance of electric drive,Also which has stable performance and good electrical conductivity.Through experiments exploring the effect of MCNT mass fraction on electric drive performance,Measured the capacitance and resistance of the electrode membranes with the different MCNT by cyclic voltammetry and AC impedance method,observing the appearance morphology by Scanning Electron Microscope(SEM),it is found that increasing the mass fraction of MCNT is beneficial to generate a porous network structure,such a special structure lead to the better electrochemical properties of the electrode membrane,thereby improving the output performance of the electric drive.Through analyzing the volt-ampere characteristic curve of the electrode film with different thickness,it is found that its electric capacity can be improved by increasing the thickness.Besides,combined with the experimental test of electric drive performance,we came to the conclusion that thicker electrode film can improve the output force and response time of electric drive,but decrease its output displacement.Furthermore,through the experimental test,the electrode film with different thickness how to affect the performance of electric drive is analyzed in details.Specifically,with the thickness of the electrode film growing,the output force and response time of electric drive increase,but its output displacement decrease.Thus,the optimal electrode film thickness is obtained,which can result in better electric drive performance.By applying different voltages to electric drive,its output performance is studied under different voltages.Currently,the life criterion suitable for artificial muscle is established,and the electric drive life has been tested.Furthermore,the driving mechanism of electric drive is analyzed,resulting in its cleared driving principle.
