PVA:Nano-eggshell microcomposite as an energy storage material for supercapacitors. J Mater Sci: Mater Electron, 9(33), p.6496-6503.10.1007/s10854-022-07823-82-s2.0-85124314157https://doi.prg/10.1007/s10854-022-07823-8https://hdl.handle.net/20.500.12415/3199The development and advantages of wearable flexible electronics have become attractive issues with excellent electrochemical performances in energy storage devices. In this study, we highlighted a low cost and green fabrication of biosupercapacitor using poly(vinyl alcohol) (PVA):Nano-eggshell microcomposites. As it is known, interest in the production of green supercapacitors is increasing rapidly. A uniform PVA:Nano-eggshell microcomposite morphology was obtained in the polymer blend-based nanostructure using kappa-carrageenan as the matrix. PVA:Nano-eggshell microcomposites were prepared and coated on a Ni foam. The performance of PVA:Nano-eggshell microcomposites-Ni foam-based supercapacitor was investigated. Kappa-carrageenan was used to increase the specific capacity due to the large number of free charges. The proposed supercapacitor showed a high specific capacitance of 255 F/g in [0, 1] V range at 100 mV/s scan rate. These results demonstrated that the proposed electrode of PVA:Nano-eggshell microcomposites is to be a promising high performance and flexible supercapacitor in energy storage applications.eninfo:eu-repo/semantics/openAccessMaterials chemistryStatistical and nonlinear physicsElectronicArticle65033364969WOS:000751260000007Q2
