“…This study shows that the synthesized samples are stable, and the residual material is larger than 60% even at 800 °C for TiO 2 /PANI/PVA and 33% at 800 °C for CdS/PANI/PVA. TiO 2 has stronger thermal stability than other materials due to the strong contacts between the nanoparticles and the polymer mix chain, these results are consistent with previous literature [30]. Figure 7 illustrates the heat flow versus temperature for the as-prepared nanocomposites with a heating rate of 10 °C min −1 .…”

The researchers used the oxidative chemical polymerization of aniline to prepare the polyaniline/polyvinyl alcohol (PANI/PVA) blend and its nanocomposites loaded with cadmium sulfide and Titanium dioxide nanoparticles (CdS-NPs & TiO2-NPs) were synthesized by aniline oxidative chemical polymerization. CdS and TiO2 were incorporated into the prepared nanocomposite to reinforce the mechanical and electrical energy storage performance. XRD revealed the presence of CdS NPs & TiO2 NPs in the polymer matrix; meanwhile, SEM confirms they are well dispersion in the polymer matrix and are dispersed well on the superficies of the synthesized nanocomposites. The presence of characteristic peaks in the Fourier transforms infrared proved the compatibility of the investigated nanocomposite. The analysis of the cyclic voltammetry, CV, confirms the possibility of using the synthesized nanocomposites as a supercapacitor electrode in a 2 M KOH electrolyte. A broadband dielectric spectroscopy was used to examine the electrical and dielectric properties of the prepared samples over a broad range of frequencies and at four selected temperatures. Therefore, this study is devoted to shedding more light on the blend's performance and nanocomposites under investigation as an electrode or even solid electrolyte in superconductor technology. The study shows that the blend behaves similarly to its two nanocomposites in the activation plot. However, the blend has higher dc-conductivity by about four orders of magnitude, an electrode polarization is developed accompanied by apparently colossal of the  values. This makes it very promising for applications in many fields of advanced microelectronics.

“…Overall, the rGO/TiO 2 /PANI nanocomposite emerges as a promising candidate for efficient and eco-friendly energy storage systems across various applications. [80] rGO, CuO & PpPD (poly-p-phenylenediamine) based novel ternary composite electrode was reported by Keihan et al for efficient supercapacitors. The binary composite CuO-rGO was synthesized by hydrothermal approach, which was later followed by in-situ polymerization of PpPD onto the exterior & interior of CuO-rGO for ternary composite (rGO/CuO/PpPD) synthesis, as shown in Figure 11.…”

Supercapacitor's demand for hybrid vehicles, portable electronic gadgets, and high‐power applications is increasing unexpectedly. However, supercapacitors′ inadequacies (i. e., inflated costs, poor energy density, erratic cycle life) need to be addressed by introducing novel composite materials and developing facile synthesis techniques which can give them high surface area and improved electrochemical stability. Moreover, hybrid supercapacitor electrodes based on ternary composites should be designed to broaden their application range and to deal with the challenges. The primary aim of this review is to explore the recent advances in the field of hybrid supercapacitors to address the challenges in this field. Specifically, we have focused on ternary nanocomposites comprising Graphene‐Conducting Polymers‐Metal Oxides (G‐CPs‐MOs) and Graphene‐Conducting Polymers‐Metal Sulfides (G‐CPs‐MSs). Our investigations centred around exploring various synthesis techniques, the surface morphology of composites and analysing the reported electrochemical evaluations of supercapacitor electrodes to highlight the potential prospects and challenges they present.

A binary polyaniline/TiO2 and varied weight ratio TiO2/PANI nanocomposite was successfully fabricated as an electrode for energy storage application. The TiO2 nanoparticles were synthesized via manual irradiation system with wavelength 256 nm and power 125 W. Polyaniline/TiO2 was then prepared by in situ polymerizing TiO2 onto aniline monomer. Polyaniline nanofibers are loaded with TiO2 to product core-shell system. The polyaniline/TiO2 nanocomposite were characterized using XRD, XPS, TEM, TGA, CP and LCR measurements. The structure properties were examined by XRD and XPS, which confirmed preparing polyaniline/TiO2 binary nanocomposite. The thermal stability was investigated using TGA and obtained high stability of polyaniline/TiO2 compared with polyaniline, while the electrochemical properties were examined by LCR measurements. The LCR measurements were appeared dielectric constant and dielectric loss for incorporating TiO2 through PANI. Varied weights ratio TiO2 was worked in increasing the stored energy ability of polyaniline. Notably, the electrochemical investigate results appear that the PANI/TiO2 has a high specific capacitance (250 F/g) compared with pure PANI (200 F/g).
