The effect of electropolymerization method on the nanoscale properties and redox behavior of poly[2-2 '-bithiophene] thin film electrodes

摘要: Abstract The cyclability and the charge storage capacity of polymer electrodes prepared using potentiodynamic potentiostatic electropolymerization techniques were studied. It was shown that potentiodynamically films featured a much higher stability reversibility doping–undoping processes approaching 100% over multiple cycles in comparison to potentiostatically films. This related difference nanoscale morphology, crystallinity degree disorder films, as evidenced by atomic force microscopy (AFM) AFM phase imaging. Specifically, it deposited more amorphous, which enabled better withstand mechanical stresses built up due repeated swelling–deswelling. methods different concentrations reactivities oligomers generated electrode vicinity. Our results suggest for applications, opposed solar cells organic electronics, is desirable use materials with an increased amorphous content.
