Atmospheric Dry Hydrogen Plasma Reduction of Inkjet‐Printed Flexible Graphene Oxide Electrodes

This study concerns a low-temperature method for dry hydrogen plasma reduction of inkjet-printed flexible graphene oxide (GO) electrodes, an approach compatible with processes envisaged for the manufacture of flexible electronics. The processing of GO to reduced graphene oxide (rGO) was performed in 1-64 s, and sp /sp +sp carbon concentration increased from approximately 20 % to 90 %. Since the plasma reduction was associated with an etching effect, the optimal reduction time occurred between 8 and 16 s. The surface showed good mechanical stability when deposited on polyethylene terephthalate flexible foils and significantly lower sheet resistance after plasma reduction. This method for dry plasma reduction could be important for large-area hydrogenation and reduction of GO flexible surfaces, with present and potential applications in a wide variety of emerging technologies.

“…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.

“…Supercapacitors, also known as ultracapacitors, are indicated as an alternative for energy storage [2][3][4], as they exhibit high power density, long cycling lifetime, fast rate of charge-discharge, short response time, good durability and safe operation [1,2,[4][5][6]. The charge storage mechanism in supercapacitors is based on electrical double-layer capacitance (EDLC), which is related with adsorption and de-adsorption of ions in the electrode material/electrolyte interface, and on pseudocapacitance, which is related to reversible Faradaic redox reactions [5,7,8].…”

“…The carbon nanomaterials including graphene (G), reduced graphene oxide (rGO), carbon fibers (CF), carbon nanotubes (CNTs), porous carbon and carbon aerogels contribute with EDLC thanks to their high electrical conductivity, excellent mechanical strength and high surface area [1,7]. Graphene is a two-dimensional nanomaterial with sp 2 hybridized carbons exhibiting high surface area, chemical stability, charge-carrier mobility, inherent flexibility and good transparency, which enable 2 of 14 its use in different applications including biosensing, photovoltaics, batteries or fuel cells [2,9,10].…”

“…Amongst the conducting polymers, polypyrrole (PPy) attracted increased interest in energy storage thanks to easy polymerization, high electrical conductivity [8], nontoxicity, high theoretical specific capacitance attributed to its good charge-storage performance in wide potential window [11,17], low cost, chemical and environmental stability [8,11,18]. Nevertheless, PPy may suffer from mechanical degradation during the intercalating/de-intercalating process which further result in limited cycling stability and high interfacial resistance [1,5,7,11,19,20].…”

Improving Electrochemical Properties of Polypyrrole Coatings by Graphene Oxide and Carbon Nanotubes

2020

Nanostructured polypyrrole coating was applied on carbon paper via simple dip-coating and electrochemical approach. Hybridization with nanocarbon materials (graphene oxide (GO) and multi-walled carbon nanotubes (MWCNTs)) and their effect as an anchoring hybrid layer for the growth of polypyrrole towards improving electrochemical properties are studied. The loading of each component and their w/w ratio were evaluated. Fourier transform infrared spectroscopy, field emission scanning electron microscopy, and Raman spectroscopy were employed to characterize the properties of the coatings. The electrochemical properties were investigated by cyclic voltammetry. The results indicated the electrodeposition of polypyrrole is enhanced by the addition of MWCNTs to the GO layer due to the formation of a hierarchical network. The electrochemical performance of the modified electrode was shown to be highly dependent on the employed w/w ratio, reaching a capacitance value of about 40 mF cm−2 for a carbon paper substrate modified with GO:MWCNT in a w/w ratio of 1:2.5 and PPy layer deposited by cyclic voltammetry for 30 cycles. The contribution to total stored charge was found to be primary from the inner capacitance component of about 95.5% contribution.
