|dc.description.abstract||This work describes the design of Ni(OH)₂@PPy-NTs core–shell nanostructures with potential application as an electrode material for supercapacitors. Initially, one dimensional (1D) polypyrrole nanotubes (PPy- NTs) were synthesized through a chemical oxidation mediated soft template-directed route using as the anion the azo dye methyl orange (MO). Subsequently, three dimensional (3D) Ni(OH)₂ nanoflakes were grown onto PPy-NTs by a simple hydrothermal route. This exclusive Ni(OH)₂@PPy-NTs nanoarchitecture helps to improve the overall electrochemical performance of the electrode, due to the high surface area provided by 3D nanoflakes and excellent electronic/ionic conductivity of 1D nanotubes. The maximum specific capacitance obtained for Ni(OH)₂@PPy-NTs was 536 F g⁻¹ with good capacity retention after 1000 charge/discharge cycles. Last but not least, EIS technique showed a low electrochemical series resistance for Ni(OH)₂@PPy-NTs confirming their promise as a high-performance energy storage material.||-|
