“…Many studies have focused on developing new electrode materials with economic processing techniques. [17][18][19][20][21] Two main charge storage mechanisms are typically involved in supercapacitors: faradaic pseudocapacitance and/or electrical double layer capacitance (EDLC). Pseudocapacitance results from reversible redox reactions on electrode material surfaces, and it usually occurs in metal oxides and conductive polymers.…”

This study evaluates DC-pulse nitrogen atmospheric-pressure-plasma-jet processed carbon nanotube (CNT)-reduced graphene oxide (rGO) nanocomposites for gel-electrolyte supercapacitor applications.X-ray photoelectron spectroscopy (XPS) indicates decreased oxygen content (mainly, C-O bonding content) after nitrogen APPJ processing owing to the oxidation and vaporization of ethyl cellulose.Nitrogen APPJ processing introduces nitrogen doping and improves the hydrophilicity of the CNT-rGO nanocomposites. Raman analysis indicates that nitrogen APPJ processing introduces defects and/or surface functional groups on the nanocomposites. The processed CNT-rGO nanocomposites on carbon cloth are applied to the electrodes of H 2 SO 4 -polyvinyl alcohol (PVA) gel-electrolyte supercapacitors.The best achieved specific (areal) capacitance is 93.1 F g À1 (9.1 mF cm À2 ) with 15 s APPJ-processed CNT-rGO nanocomposite electrodes, as evaluated by cyclic voltammetry under a potential scan rate of 2 mV s À1. The addition of rGOs in CNTs in the nanoporous electrodes improves the supercapacitor performance.

“…APP with low gas temperature has been used for applications in biomedicine, food processing, and agriculture [29,30]. An APP with an intermediate gas temperature (of the order of several hundred degrees Celcius) can be used for rapid materials processing by taking advantage of the synergetic effect of heat and reactive plasma species [28,[31][32][33][34][35][36][37][38][39][40][41]. APP has been used to oxidize the AA6061-T6 aluminum alloy surface for strong and durable adhesive bonding applications [42].…”

Surface condition and corrosion resistance are major concerns when metallic materials are going to be utilized for applications. In this study, FeCoNiCr medium-entropy alloy (MEA) is first treated with a nitrogen atmospheric-pressure plasma jet (APPJ) and then coated with octadecyltrichlorosilane (OTS) for the surface modification. The hydrophobicity of the FeCoNiCr MEA was effectively improved by OTS-coating treatment, APPJ treatment, or the combination of both treatments (OTS-coated APPJ-treated), which increased the water contact angle from 54.49° of the bare MEA to 70.56°, 93.94°, and 88.42°, respectively. Potentiodynamic polarization and electrochemical impedance spectroscopy tests demonstrate that the APPJ-treated FeCoNiCr MEA exhibits the best anti-corrosion properties. X-ray photoelectron spectroscopy reveals that APPJ treatment at 700 °C oxidizes all the alloying elements in the FeCoNiCr MEA, which demonstrates that a short APPJ treatment of two-minute is effective in forming a metal oxide layer on the surface to improve the corrosion resistance of FeCoNiCr MEA. These results provide a convenient and rapid method for improving surface properties of FeCoNiCr MEA.

“…[32][33][34] APPJ with medium temperature (400-700 C) has demonstrated rapid materials processing capability owing to the synergetic effect of reactive plasma species and heat. [35][36][37][38] In this study, a scan-mode nitrogen DC-pulse APPJ is used to treat NiO for PSCs. The peak temperature of the substrate during APPJ operation is $500 C. The optical transmittance, haze spectra, surface morphology, chemical bonding conguration, wettability, conductivity, and electrochemical properties of scanning APPJ-treated NiO are characterized.…”
