Electrochemical polymerization of 4,4′-thiobis-phenol in alkaline solution and properties of polymer
The electrochemical polymerization of 4,4′-thiobis-phenol in different concentrations of alkaline media has been carried out using cyclic voltammetry. Electrochemical autocatalytic reaction of poly(4,4′-thiobis-phenol) (TDP) in a high concentration of alkaline medium was verified by potentiostatic and galvanostatic electrolysis. PolyTDP showed different electrochemical activities in solutions with different pH. The electrochemical impedance spectroscopy (EIS) was used to characterize the polyTDP. The visible and FT-IR spectra of polyTDP were also measured. Scanning electron microscopy showed that the prepared polyTDP film exhibited a dense, uniform structure, which makes it a potential material for sensor construction.
