研究了3-噻吩基甲基二硫醚与苄基二硫醚的共聚反应。以一种新颖的简便方法合成了两种单体。它们的共聚物，尤其是聚（3-噻吩基甲基二硫醚-co-苄基二硫醚），在Pt、Au或玻璃碳电极上，当TcB为1：4时，容易在较低电位下电共聚形成稳定的高电致发光结构。TcB_（1：4）和TcB_（4：1），尤其是TcB_（1：4），比纯的聚3-噻吩基甲基二硫醚和聚苄基二硫醚具有更好的电导率。用循环伏安法测定了共聚物的比表面积。共聚物显示出比单体本身提供更多的功率和能量的能力。由于共聚物的官能团在80 ℃之前不会被破坏，因此可用作锂二次电池的正极材料。在扫描电子显微镜下，共聚物显示出较大的嵌段结构。结果表明，该共聚物具有作为正极材料的潜力
The copolymerization of 3-thienylmethyl disulfide and benzyl disulfide has been investigated. Two monomers were synthesized in a novel facile way. Copoly- mer of them, especially poly (3-thienylmethyl disulfide-co- benzyl disulfide), ratio 1 : 4, namely, TcB1:4, was easily electrocopolymerized to form a stable and higher conduc- tive structure at a lower potential on Pt, Au, or glass car- bon electrode. TcB1:4 and TcB4:1, especially the former, exhibit better conductivities than those of pure poly 3-thie- nylmethyl disulfide and poly benzyl disulfide. The copoly- mer has larger areas than that of monopolymer by cyclic voltammogram measurement. The copolymer shows a capability of supplying more power and energy than monopolymer itself. Copolymers could be used as cathode materials for lithium secondary batteries because their functional groups could not be destroyed before 80 � C. In scanning electron micrography, the copolymers show larger compacter structure. The results of the copolymer systems show that they are potentials as cathode materials
