报道了用于有机自由基电池的三维有序大孔（3DOM）氮氧聚合物刷电极的制备及其电化学性能。以聚苯乙烯胶体晶体为模板，通过电聚合聚吡咯、表面引发剂改性、表面引发原子转移自由基聚合等方法制备了3DOM电极。3DOM电极的放电容量与反蛋白石的厚度成正比。3DOM电极在5C放电速率下的放电容量是平面电极的40倍;其循环寿命性能在250次循环后表现出96.1%的保持率。
The synthesis and electrochemical performance of three-dimensionally ordered macroporous (3DOM) nitroxide polymer brush electrodes for organic radical batteries are reported. The 3DOM electrodes are synthesized via polystyrene colloidal crystal templating with electropolymerization of polypyrrole, modification of surface initiator, and surface-initiated atom transfer radical polymerization. The discharge capacity of the 3DOM electrodes is proportional to the thickness of the inverse opal. The discharge capacity of the 3DOM electrode at a discharge rate of 5 C is 40 times higher than that of the planar electrode; its cycle-life performance exhibits 96.1% retention after 250 cycles.
