Hierarchical Design of Polymer?Metal Oxide?Carbon Architectures for High-Performance Supercapacitor Electrodes

초록

Three-dimensional hierarchical composites integrating carbon nanofibers, transition metal oxides, and an outermost conducting polymer layer are fabricated via sequential synthesis for high-performance supercapacitor electrodes. The carbon nanofiber provides a robust conductive framework, while uniformly distributed metal oxides enhance pseudocapacitive behavior. In addition, the incorporation of a polymer layer improves conductivity and prevents structural degradation during cycling. This multi-layered design enables synergistic interactions between the carbon framework, redox-active oxides, and conducting polymer, resulting in superior charge-storage efficiency and structural integrity. These results demonstrate a versatile strategy for designing stable and high-performance supercapacitors, offering significant potential for future energy storage technologies. - 본 연구는 2025년도 산업통상자원부 및 산업기술기획평가원(KEIT) 연구비 지원에 의한 연구임(RS-2022-00156073).
