An Alternative Route to Prepare Polymelamine by Electropolymerization in Deep Eutectic Solvents Containing Water

An alternative route is offered for the electrodeposition of polymelamine (pMel) by electropolymerization in deep eutectic solvents, which has been proposed previously (Electrocatalysis 12:238-250, 2021) but difficultly synthesizing pMel in (Electrocatalysis 14:131-137, 2023). The introduction of a modest amount of water as an additive into deep eutectic solvents enables the electropolymerzation of melamine to pMel on carbon electrodes. The electrochemical behavior and catalytic activity of active chlorine species in different proportions of water-containing deep eutectic solvents was studied carefully by cyclic voltammetry. Electrochemical quartz crystal microbalance and atomic force microscopy studies confirmed the mass changes and nanostructure formation that occurred during pMel deposition.
