This research looks at ways of tailoring and improving the stiffness of polypyrrole hydrogels for use as flexible supercapacitor electrodes. Molecules providing additional cross-linking between polypyrrole chains are added post-polymerisation but before gelation, and are found to increase gel stiffness by up to 600%, with the degree of change dependent on reactant type and proportion. It was also found that addition of phytic acid led to an increase in pseudocapacitive behaviour of the hydrogel, and thus a maximum specific capacitance of 217.07 F·g−1 could be achieved. This is an increase of 140% compared to pristine polypyrrole hydrogels produced by this method.

分子剪裁以提高聚吡咯水凝胶的刚度和电化学储能能力

这项研究着眼于定制和改善用作柔性超级电容器电极的聚吡咯水凝胶的硬度的方法。在聚合后但在胶凝之前添加在聚吡咯链之间提供额外交联的分子,并发现其胶凝强度最多提高600%,其变化程度取决于反应物的类型和比例。还发现添加植酸导致水凝胶的假电容行为增加,因此可以实现最大比电容为217.07 F·g -1。与通过这种方法生产的原始聚吡咯水凝胶相比,增加了140%。
