The composites of poly[Ni(salen)] and multi-walled carbon nanotube(MWCNT) were synthesized by pulse potentiostatic method.The composites were characterized by field emission scanning electron microscopy,Fourier transform infrared spectra,and electrochemical impedance spectroscopy.The wrapping of carbon nanotubes with poly[Ni(salen)] varied significantly with anodic pulse duration.Variance of structure of poly[Ni(salen)] caused by anodic pulse duration affected the ability of absorption to solvent molecules or solvated ions,which was indicated by ν(C≡N) intensity.The ability to store/release charge of poly[Ni(salen)] caused by redox switching was evaluated in the form of low-frequency capacitance.Correlations of chargetransfer resistance/ionic diffusion resistance with potential and anodic pulse duration were investigated.
