Abstract
Organic polymer plating properties of 6-diallylamino-1, 3, 5-triazine-2, 4-dithiol monosodium (DAN) were studied for NaNO2 supporting electrolytes. Supporting electrolytes cause polymer film to form or not. NaNO2 electrolytes particularly accelerated the formation rate of polymer plating. The accelerating effect of NaNO2 was confirmed comparing plating potentials in the presence of NaNO2 and NaCO3. NO2- anions are electrochemically oxidized to yield NO2·radicals that react with DAN to yield thiyl radicals. DAN thilyl radicals between molecules, yielding disulfide bonds that grows into polymer films. Organic polymer plating films contained disulfide and monosulfide bonds produced by the reaction between allyl groups and thiyl radicals and network chains.
