Terpolymer film formation and its capacitor performance

Electrocoated Films of Poly(N-Methylpyrrole-co-2,2′-Bithitiophene-co-3-(Octylthiophene)), Characterizations, and Capacitor Study

N-Methylpyrrole (N-MPy), 2,20-bithiophene (BTh), and 3-(Octylthiophene) (OTh) were electrocopolymerized in 0.2M NaClO4= CH3CN on glassy carbon electrode (GCE). The resulting terpolymers of N-MPy, BTh and OTh in different initial monomer feed ratios such as [N-MPy]0=[BTh]0=[OTh]0¼1=1=1 and 1=2=5 were characterized by cyclic voltammetry (CV), Fourier-transform infrared attenuated total reflectance spectroscopy (FTIR-ATR), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX),
