Ruthenium oxide–carbon-based nanofiller-reinforced conducting polymer nanocomposites and their supercapacitor applications

Abstract

In this review article, we have presented for the first time the new applications of supercapacitor technologies and working principles of the family of RuO 2-carbon-based nanofiller-reinforced conducting polymer nanocomposites. Our review focuses on pseudocapacitors and symmetric and asymmetric supercapacitors. Over the last years, the supercapacitors as a new technology in energy storage systems have attracted more and more attention. They have some unique characteristics such as fast charge/discharge capability, high energy and power densities, and long stability. However, the need for economic, compatible, and easy synthesis materials for supercapacitors have led to the development of RuO 2-carbon-based nanofillerreinforced conducting polymer nanocomposites with RuO 2. Therefore, the aim of this manuscript was to review RuO 2-carbon-based nanofiller-reinforced conducting polymer nanocomposites with RuO 2 over the last 17 years.

Research Progress on Porous Carbon Supported Metal/Metal Oxide Nanomaterials for Supercapacitor Electrode Applications

“…), or a conductive polymer such as PANI, PPy, etc. 116,117 RuO 2 is highly pseudocapacitive, yielding 90% charges stored through the oxidation−reduction reaction during the charge−discharge process, and the rest by the EDLC type of storage. The improvement can be attributed to the mixed ion/ electronic pathway.…”

Investigation on Tribological and Thermo-Mechanical Properties of Ti3C2 Nanosheets/Epoxy Nanocomposites

“…Incorporating inorganic or organic fillers into the polymer matrix is a fascinating method for improving the mechanical, tribological, thermal, and/or electrical properties of the polymer matrix. − Over the past few decades, the tribological or other properties of filler-incorporated epoxy composites have been widely investigated. Research studies show that many kinds of microfillers/nanofillers, including TiO 2 , Al 2 O 3 , polytetrafluoroethylene, graphite, MoS 2 , and so forth, are able to effectively improve the tribological or mechanical properties of the epoxy matrix. − By preparation of micro- and nano-TiO 2 -incorporated epoxy composites, Jochheim demonstrated that the TiO 2 nanoparticles imparted a better wear resistance to the epoxy matrix than the TiO 2 microparticles, mainly attributed to the fact that the nanosized TiO 2 had a higher surface area originating from the small size effect, thereby inducing a stronger interfacial interaction between nano-TiO 2 and the epoxy matrix.…”

Effect of Carbon Fillers on the Wear Resistance of PA6 Thermoplastic Composites

“…As reinforcements, different microfillers in the shape of fibers [ 1 , 2 , 3 ], powders [ 4 , 5 ], or nanofillers [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ] are used. Metal particles, ceramic powders or fibers, and natural fibers are widely applied as reinforcements as well.…”
