摘要: 聚有机二硫化物的电化学性质,受到与它共聚的有机基团的影响.为此,我们以对苯二甲醚为原料经氯甲基化、硝酸氧化、与二硫化钠缩合制得了醌-硫硫共聚物,并用循环伏安法研究了该种共聚物的电化学性质,讨论了有机基团对-S-S-键电化学性质的影响,并组装成电池研究它的放电行为.研究结果表明:有机基团对醌-硫硫聚合物电化学性质的影响,主要表现在氧化还原峰及电池的开路电压和放电平台的位置的改变.

Abstract: Organic polydisulfide containing quinonoid structure was synthesized by chloromethylation, oxidation by nitric acid, and condensation polymerization with sodium disulfide. The effect of quinonoid structure on the electrochemical behavior of organic polydisulfide was investigated with cyclic voltammetry and chargedischarge measurement. The result shows that quinonoid struture mainly affects the positions of redox peaks of organic polydisulfide, open circuit voltage and discharge platform voltage of cell with the organic polydisulfide as cathode.
