(a) Plot of the electro-oxidation peak current of FLFT versus the number of electro-polymerization cycles. (b) CVs for the electro-polymerization of TY-G (1.0 mM) in PB (0.2 M and 7.0 pH) on the surface of MWCNTPE at the potential scan rate of 0.1 V/s and the potential interface of − 0.60 to 1.40 V versus Hg₂Cl₂.
