“…The third category is also pseudo-capacitor based on faradic reactions, but the electrode materials are electronically conducting polymers [36], or their composites such as polypyrrole (PPy) [37,38], polyaniline (PANi) [39,40], poly(3,4-ethylenedioxythiophene) (PEDOT) [41], and so on. This type of conducting polymers has a relatively high conductivity, and a relatively low cost compared to carbon-based electrode materials [42].…”

“…The SC measured values are 411.52, 460.56 and 552.11 Fg -1 for PANi, 5 wt% MWCNT and 10 wt% MWCNT, respectively. In the assessment to the pure PANi, the nanocomposites demonstrate higher SC which is also greater than microwaveassisted [27], solid-state [10] and chemical synthesized [28] of PANi/MWCNT nanocomposites reported by other investigators. Nano-sized tubular particles with cancellous and obtainable highly mesoporosity features may provide a large surface area and permit outstanding electrolyte admission and saved in three dimensions.…”

A new approach involving low-temperature system has been developed for the polyaniline/multi-walled carbon nanotubes (PANi/MWCNT) composite in which MWCNT are coated with a layer of PANi in a complete tubular morphology. The MWCNT content varied from 0 to 10 %. The effect of MWCNT content on the thickness of PANi layer was studied. SEM technique was used to investigate the morphology and changes in the dimension of nanotubes. The interaction between PANi and MWCNT considering the nature of chain growth has been explained according to the results of FT-IR analysis. The improvement of thermal stability and crystallinity of the nanocomposites has been evaluated by using TGA and XRD, respectively. The results show the thickness of PANi coating on the surface of MWCNT was depended on the MWCNT content. These nanocomposites have been used for supercapacitor electrodes. The galvanostatic chargedischarge measurements indicated that the PANi/MWCNT composites had greater specific capacitances than pure PANi.

“…Figure 9 shows the galvanostatic charge-discharge behavior of the pure PProDOT and PProDOT/SnO 2 nanocomposites from different methods, which are carried out in 1 M H 2 SO 4 at the current density of 3 mA cm specific capacitance (SC) of active material has been evaluated from the charge-discharge curves. According to equation: SC=(I 3 Dt)/(DV 3 m), where I is chargedischarge current, Dt is the discharge time, DV is the electrochemical window (1 V), and m is the mass of active materials within the electrode (3 mg) [50]. As shown in Fig.…”

In this study, the poly(3,4-propylenedioxythiophene)/ SnO 2 nanocomposites (PProDOT/SnO 2 ) with different contents of SnO 2 were successfully prepared by using hand grinding and ball milling methods, respectively. The effects of the synthesis methods and SnO 2 on the structure and electrochemical properties of the nanocomposites were deeply discussed. The results showed the structure of composites were highly affected by the increasing amount of nano-SnO 2 particles in reaction medium of hand grinding method than ball milling method. And, the PProDOT/SnO 2 nanocomposites from ball milling method displayed similar absorption spectra, and ball milling method promoted the uniform distribution of nano-SnO 2 particles in PProDOT matrix. However, PProDOT/SnO 2 nanocomposites from hand grinding method displayed the higher specific surface area and stronger synergetic effects between PProDOT and SnO 2 than that of PProDOT/SnO 2 nanocomposites from ball milling method. As a result, the PProDOT/SnO 2 nanocomposites from hand grinding method showed higher electrochemical activity than PProDOT/SnO 2 nanocomposites from ball milling method. Moreover, the specific capacitance and cycle stability of PProDOT/SnO 2 nanocomposites from both methods were higher than respective pure PProDOT. Among all the nanocomposites, PProDOT/15wt%SnO 2 nanocomposite from hand grinding method possessed the highest specific capacitance (259 F g 21
