摘要

Strontium oxide nanoparticles were distributed over a polyaniline (PANI) network prepared through a hydrothermal process followed by a polymerisation process. In that SrO/PANI complex network and their morphology, structural, surface area and vibrational modes were detailed analysed through the various physico-chemical studies. In XRD and SEM analysis, the SrO/PANI nanocomposites exhibited cubic crystalline and sheet-like structures. Further, these composite materials achieved the specific area range of 73.08 m2 g− 1, respectively. In supercapacitor studies, the SrO/PANI nanocomposites electrode was revealed to have pseudocapacitive charge storage behaviour in nature in a 1 M Na2SO4 electrolyte medium. Moreover, this half-cell electrode system the SrO/PANI composite electrode attained the capacitance of 252 F g− 1 along with 95% stability retention after 3000 cycles. In view of this electrochemical behaviour, the metal oxide/polymer (SrO/PANI) complex matrix will be suitable for potential devices in future.
