Title: | Polyaniline–MnO2 coaxial nanofiber with hierarchical structure for high-performance supercapacitors | Authors: | Jiang, Hao Ma, Jan Li, Chunzhong |
Keywords: | DRNTU::Engineering::Materials | Issue Date: | 2012 | Source: | Jiang, H., Ma, J., & Li, C. (2012). Polyaniline–MnO2 coaxial nanofiber with hierarchical structure for high-performance supercapacitors. Journal of Materials Chemistry, 22(33), 16939-16942. | Series/Report no.: | Journal of materials chemistry | Abstract: | We demonstrated the facile loading of ultrafine and loosened K-birnessite MnO2 floccules on the surface of polyaniline (PANI) nanofibers by simply soaking the polyaniline nanofibers in a KMnO4 aqueous solution for electrochemical energy storage applications. The as-prepared PANI–MnO2 coaxial nanofibers with optimal composition, when applied as an electrode, exhibited a high specific capacitance (383 F g−1 at 0.5 A g−1) with good rate and cycling stability in 1 M Na2SO4 aqueous solution. Such intriguing electrochemical performance is mainly attributed to the synergistic effects of the combined pseudo-capacitive contributions from the core and shell. The present findings promoted the development of advanced electrode materials, exhibiting huge potential for supercapacitors. | URI: | https://hdl.handle.net/10356/96592 http://hdl.handle.net/10220/11401 |
