“…For electrochemical capacitors, focus has been on nanostructured carbons, nanotubes, and nanotemplates. 10,11 Among these materials, carbon nanotubes (CNTs) have been considered ideal for electrochemical capacitors, owing to the advantages such as accessible surface area, excellent electronic conductivity, and good stability. [12][13][14][15][16][17] On the other hand, CNT grows the polarization when CNT electrode reacts with electrolyte through the electrode/electrolyte interface.…”

To reduce polarization of electrochemical capacitor based on carbon nanotube, titanium oxide nanoparticles were deposited by ultrasound. The pore distribution of TiO2/CNT nanoparticle exhibited surface area of 341 m 2 g -1 when TiO2 content was 4 wt %, which was better than that of pristine CNT with surface area of 188 m 2 g -1 . The analyses indicated that titanium oxide (particle diameter < 20 nm) was deposited on the CNT surface. The electrochemical performance was evaluated by using cyclic voltammetry (CV), impedance measurement, and constant-current charge/discharge cycling techniques. The TiO2/CNT composite electrode showed relatively better electrochemical behaviors than CNT electrode by increasing the specific capacitance from 22 Fg -1 to 37 Fg -1 in 1 M H2SO4 solution. A symmetric cell assembled with the composite electrodes showed the specific capacitance value of 11 Fg -1 at a current loading of 0.5 mAcm -2 during initial cycling.

“…The use of PANI-CNT composite as an electrode in a hybrid capacitor has been suggested first by Frackowiak and Beguin [106]. In the past few years, many attempts have been made to improve the capacitance of PANI-CNT-based devices [107][108][109][110][111][112][113][114]. The details of the cell construction with the experimental values of capacitance obtained in these studies are presented in Table 1.…”

Abstract:The key developments in polyaniline-carbon nanotube (PANI-CNT) composites are reviewed. Apart from in situ chemical polymerization and electrochemical deposition, a number of interesting approaches including the use of aniline functionalized CNTs and ultrasound/microwave/γ-radiation initiated polymerization have been used in the preparation of composites. The structure and properties of these composites have been investigated by a variety of techniques including absorption, infrared (IR), Raman, X-ray photoelectron spectroscopy methods, scanning electron and scanning probe microscopy techniques, cyclic voltammetry, and thermogravimetry. The experimental results indicate favorable interaction between PANI and CNTs. The CNT content in these composites controls their conductive, mechanical, and thermal properties. The most interesting characteristic is their easy dispersibility in aqueous solution. The performance evaluation studies of PANI-CNT composites in a number of applications including supercapacitors, fuel cells, sensors, and actuators are highlighted.

“…7,12 Currently, most of the research is focused on searching for composite electrode materials with superior electrochemical performance in order to satisfy future applications. Conducting polymer polyaniline (PANI) incorporated with transition metal dichalcogenides, 13,14 graphene oxide, 15 graphene, 16,17 carbon nanotube 18 and so on 19,20 have been reported to not only achieve higher capacitive performance, but also to solve the problem of poor cycle life of PANI. Among these composite electrode materials, the polymerization of aniline is triggered by chemical oxidation, 21 electrochemistry, 22 solution mixing, 23 self-assembly 24 and Pickering emulsion.…”

Supercapacitors as a promising energy storage device have received significant attention. Here we report a facile, low cost and mass production strategy to prepare polyaniline (PANI)/ molybdenum sulfide (MoS X ) supercapacitor material by electrodeposition. More specifically, PANI was electrodeposited on glassy carbon (GC) through chrono amperometry followed by electrodeposition of MoS X via chrono potentiometry from ammonium tetrathiomolybdate ((NH 4 ) 2 MoS 4 ) precursor. This composite material was characterized by X-ray photoelectron spectrum, scanning electron microscopy and energy-dispersive X-ray spectroscopy. In addition, PANI/MoS X shows superior capacitance of 48.64 mF cm ¹2 at a current density of 56.62 A cm ¹2 and long-term stability without any degradation during the 150 cycles. The enhanced capacitance observed is from the combination of electrochemical behaviors of PANI and MoS X .
