Summarize on Application of Electrochemical Quartz Crystal Microbalance Technique in Conducting Polymer Research
Conducting polymers,as a class of polymer materials with high electrical conductivity and good electrochemical properties,are widely used in sensors,batteries,and flexible electronics.Electrochemical quartz crystal microbalance(EQCM)is a detection technology with sensitivity up to nanogram level,which can provide in-situ mass change information in the process of electrochemical reaction.It has the advantages of high sensitivity and high resolution,and has become a powerful tool for studying conducting polymers.In this paper,the application of EQCM technology in the field of conducting polymers in recent years is reviewed,including the synthesis mechanism of polymer membranes,ion exchange and mass transfer mechanism,as well as the application in energy conversion and storage.These studies are expected to provide technical support and reference for further understanding the electrochemical behavior and performance regulation of conducting polymers.
