Development of PANI based ternary nanocomposite with enhanced capacity retention for high performance supercapacitor application

A robust approach for designing N‐doped reduced graphene oxide/polyaniline nanocomposite‐based electrodes for efficient flexible supercapacitors

“…In addition diffraction peak broadening for both rGO and N‐rGO indicates the random orientation of GN layers after the reduction process 36 . For PANI, three characteristic less intensive diffraction peaks at 2θ ~14°, ~20°, and 24° are observed which are corresponds to the (011), (020), (200) crystal planes of PANI 30,37,38 . The diffraction peaks at 14° and 24° are assigned to the periodicity parallel and perpendicular to the polymer chain, respectively 28 .…”

Recent progress in polyaniline-based composites as electrode materials for pliable supercapacitors

“…73 A ternary composite consisting of PANI, N-doped graphene, and copper chromate was developed by Ghosh's group, which exhibited better performance than the pristine PANI. 74 The aforementioned examples proved that PANI-based composites can improve the capacitance, energy density, and ability to retain the specific capacitance over repeated charge–discharge cycles. Similar strategies were adopted by researchers to obtain excellent results in the case of flexible SCs.…”

One‐step Electrodeposition Synthesis of Ni(OH)2/PANI/rGO for High‐performance Supercapacitor Electrodes

“…[19][20][21][22][23] Polyaniline, a conducting polymer, can be easily prepared and has many advantages such as high conductivity, good reversibility, high specific capacitance, etc. [24][25][26][27][28] Nickel hydroxide as the electrode material also has outstanding merits of low cost, high theoretical specific capacitance, convenient preparation and high security. [29][30][31][32][33] The use of non-faradaic materials with high surface area like graphene and graphene oxide in combination with pseudocapacitive materials like metal oxide/hydroxide (NiO, Ni(OH) 2 , etc.,) and conducting polymers like polyaniline (PANI), polypyrrole (PPy), polythiophene (PT), etc., are recognized to be the promising way to attain high E, as the combinations mitigate the limitations and capitalize on the merits of them, when integrated.…”
