6-ジアリルアミノ-1, 3, 5-トリアジン-2, 4-ジチオールの有機めっきにおよぼすNaNO_2の促進作用 [in Japanese] Accelerating Effect of NaNO_2 on Organic Polymer Plating of 6-diallylamino-1, 3, 5-triazine-2, 4-dithiols [in Japanese]

Organic polymer plating properties of 6-diallylamino-1, 3, 5-triazine-2, 4-dithiol monosodium (DAN) were studied for NaNO<sub>2</sub> supporting electrolytes. Supporting electrolytes cause polymer film to form or not. NaNO<sub>2</sub> electrolytes particularly accelerated the formation rate of polymer plating. The accelerating effect of NaNO<sub>2</sub> was confirmed comparing plating potentials in the presence of NaNO<sub>2</sub> and NaCO<sub>3</sub>. NO<sub>2</sub><sup>-</sup> anions are electrochemically oxidized to yield NO<sub>2</sub>·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.
