通过将氧化还原功能化的商用碳纳米管片与 H2SO4/PVA/H2O 聚合物水凝胶电解质集成，可以实现柔性全固态超级电容器的高通量生产。使用 X 射线光电子能谱和 X 射线衍射检查原始和 0.02M 高钌酸钾处理的多壁碳纳米管 (MWCNT) 片的化学成分、元素氧化态和结晶度。在组装的基于水凝胶的超级电容器电池中，氧化钌装饰的MWCNT片电极在1.0A/g下表现出96F/g的比电容和良好的循环稳定性。
High-throughput production of flexible, all-solid-state supercapacitors can be accomplished by integrating redox-functionalized commercial carbon nanotube sheets with H2SO4/PVA/H2O polymer hydrogel electrolyte. The chemical composition, elemental oxidation states, and crystallinity of the pristine and 0.02M potassium perruthenate-treated multi-walled carbon nanotube (MWCNT) sheets are examined using X-ray photoelectron spectroscopy and X-ray diffraction. In assembled hydrogel-based supercapacitor cells, ruthenium oxide-decorated MWCNT sheet electrodes exhibit a specific capacitance of 96F/g at 1.0A/g and good cycle stability.
