“…Figure 6 e shows the best result for the PPyCDC in aqueous solvent in the range of 135 ± 11 F cm −3 at ±0.2 A cm −3 . Similar values for PPy with porous carbon materials [ 4 ] were found in a comparable range of 107 F cm −3 . In contrast, the charge/discharge time depreciation was the factor determining the achievement of a higher capacitance [ 56 ].…”

“…Carbon materials (electric double-layer capacitors, non-faradaic process [ 1 ]) are poor conductors, while pseudo-capacitors [ 2 ] such as polypyrrole (redox reactive, faradaic process) are conductive in the charged state. In most cases, these are combined [ 3 ], forming hybrid materials with an enhanced capacitance and with promising results [ 4 ] for a new generation of supercapacitor devices. Focusing on specific applications, such as smart textiles, materials with actuation properties for conducting polymers have recently been described [ 5 ].…”

Researchers have focused on incorporating porous carbon particles such as carbon-derived carbon (CDC) into polypyrrole (PPy), preferably on the surface, to achieve high-capacitive electrodes. Less attention is afforded to their linear actuation properties. Therefore, in this work, we chose two different electropolymerization processes using the typical PPy doped with dodecylbenzene sulfonate (DBS−) and added CDC particles, compared with CDC with phosphotungstic acid (PTA), forming CDC-PT4− dopants. The resulting PPy/DBS-CDC (PPyCDC) and PPy/DBS-CDC-PT (PPyCDC-PT) films showed different morphologies, with PPyCDC having the most CDC particles on the surface with less surrounding PPy, while in PPyCDC-PT, all the CDC particles were covered with PPy. Their linear actuation properties, applying electrochemical techniques (cyclic voltammetry and square wave potential steps), were found to enhance the PPyCDC-PT films in organic (2-times-higher strain) and aqueous electrolytes (2.8-times-higher strain) in an applied potential range of 0.8 V to −0.5 V. The energy storage capability found for the PPyCDC was favorable, with 159 ± 13 F cm−3 (1.2 times lower for PPyCDC-PT) in the organic electrolyte, while in the aqueous electrolyte, a result of 135 ± 11 F cm−3 was determined (1.8 times lower for PPyCDC-PT). The results showed that PPyCDC was more favorable in terms of energy storage, while PPyCDC-PT was suitable for linear actuator applications. The characterization of both the film samples included scanning electron microscopy (SEM), Raman, FTIR, and energy-dispersive X-ray (EDX) spectroscopy.

“…These mentioned charge carriers allow a strong delocalization of electrons that can now flow freely along with polymer conjugation without much resistance to the band gap. In some cases, the conductivity observed in intrinsically CP is close to metallic materials [39]. Regarding reduction (p-type doping), it is not ccommon because the intrinsically conducting polymers are electron-rich components, which means that they will not allow accepting a negative charge.…”

Polymer-Magnetic Semiconductor Nanocomposites for Industrial Electronic Applications

Nanocomposite materials have acquired great importance, as have similar composite materials on a macroscopic scale, because the reinforcement complements the defects in the properties of the matrix, thus obtaining materials with better mechanical, thermal, and electrical properties, among others. At the same time, the importance and research of polymeric nanocomposites reinforced with nanoparticles of various types have grown. Among those that have stood out the most in the electronics industry are polymeric matrices reinforced with nanoparticles that present dual behavior, that is, both magnetic and semiconductor. This property has been very well used in developing electronic devices such as televisions, computers, and smartphones, which are part of everyday life. In this sense, this review presents a compilation of the synthetic methods to produce polymer nanocomposites with dual magnetic and semiconductor behavior and their potential applications within electronic fields and new relevant trends.
