All the initial monomer concentrations (from 0.1 M to 1 M) were electrodeposited in 0.1 M sodium perchlorate (NaClO4) / acetonitrile (ACN) solution and characterized by cyclic voltammetry (CV), ex-situ FTIR attenuated total reflectance spectroscopy (FTIR - ATR), and scanning electron microscopy (SEM). The electrochemical impedance spectroscopic measurements of polythiophene (PT) and poly (2-methyl thiophene) (PMT) were given comparatively. The existence of a capacitance behavior is shown by Nyquist, Bode magnitude, Bode-phase, Admittance plots relationship. The T-deposited electrode in the initial monomer concentration of 0.5 M exhibits high specific capacitance of 1.13 F g(-1), in comparison with a value of 6.35 mF g(-1) for MT modified electrode in the initial monomer concentration of 0.2 M.eninfo:eu-repo/semantics/closedAccessPolythiophenemodified carbon fiber microelectrodeselectrochemical impedance spectroscopyPolymer-Coated ElectrodesFilm ElectrodesReactive GroupsConducting PolymersPoly(3-Methylthiophene)CopolymerizationCompositesCarbazoleKineticsBehaviorArticle47980992Q2WOS:000272246000008
