Hierarchical assembly of graphene/polyaniline nanostructures to synthesize free-standing supercapacitor electrode

Facile synthesis of rod-like Bi 2 O 3 nanoparticles as an electrode material for pseudocapacitors

“…The specific capacitances reported herein are much larger than that 98 F g -1 of Bi 2 O 3 thin films [24] and 94 F g -1 of reduced graphene oxide-bismuth oxide composite material [35]. Capacitive property of the Bi 2 O 3 is also comparable to some other novel composites, for instance, activated graphene quantum dots [36] and graphene/PANI composite [37] with specific capacitances of 236 F g -1 and 448 F g -1 , respectively.…”

Size-dependent capacitance of NiO nanoparticles synthesized from Ni-based coordination polymer precursors with different crystallinity

“…The specific capacitance for NiO-19 nm was determined to be 165, 154, 150, 145, and 134 F g À1 at scan rates of 10, 20, 30, 50 and 100 mV s À1 , respectively. Although there are some reports on different materials showing much higher specific capacitances [29][30][31], it still can compare with other recent reports on NiO architectures [8,13,32,33]. CV currents are directly proportional to the scan rates of CV, which demonstrates that, an ideal capacitive behaviour.…”

Preparation of a long-alkyl-chain silane grafted organic montmorillonite and its nanocomposite with SEBS

“…Montmorillonite (MMT), known as clay, is toxicologically safe nanofiller with layered silicates structure [10], while can bring a remarkable improvement in physical, mechanical [11] and barrier properties [12][13][14] of most polymers, even at very low concentration. Like other nanofiller, such as grapheme [15], carbon nanotube [16], the state of exfoliation, concentration and orientation of nanoclay, as well as the structure of polymer matrix are believed to be the key factor in achieving optimum properties of the nanocomposites [17,18]. Another important factor is considered to be an appropriate interfacial interaction between the nanofillers and the polymer matrix, depending upon the processing procedure [19][20][21][22].…”
