Electrocharacteristics of Electrochemical Synthesizing Poly(paraphenylene) Film
摘要
Abstract
Poly(paraphenylene)(PPP) film was electrosynthesized on Pt electrode by cyclic voltammetry method.The composite of PPP film was characterized by FTIR and XPS,and the relationship between film electrochemical properties and electrochemical conditions were studied using cyclic voltammetry and in situ spectroelectrochemical techniques.The results show that PPP is composed of an average of about 10.8 phenyl rings.Its conductivity was in the range of 2.0-5.0S/cm.The doping amount of PPP film reached 25% after the PPP film equilibrating at 0.6V in an electrolyte solution for 10min.Furthermore,the film had good electrochemical redox doping ability at the potential range of 0 to 1.0V.Through the EIS analysis,the PPP film's doping level increased with applied potential rising,reaction resistance Rct decreased from 329.7Ω cm2 (0V) to 15.60Ω cm2 (0.6V),while double layer capacitance Cdl increased from 1.164 Ω cm2 (0V) to 172.7Ω cm2 (0.6V).The change of these parameters validated the film in the doping process formed opening structure,which was beneficial to the ions and solvent exchanging between the film and solution.关键词
