The Influence of Graphene Oxide Composition on Properties of Surface-Modified Metal Electrodes

Abstract

The present paper describes the effect of the concentration of two graphene oxides (with different oxygen content) in the modifier layer on the electrochemical and structural properties of noble metal disk electrodes used as working electrodes in voltammetry. The chemistry of graphene oxides was tested using EDS, FTIR, UV–Vis spectroscopy, and combustion analysis. The structural properties of the obtained modifier layers were examined by means of scanning electron and atomic force microscopy. Cyclic voltammetry was employed for comparative electrochemical studies.

Flexible Transparent Electrode Based on Ag Nanowires: Ag Nanoparticles Co-Doped System for Organic Light-Emitting Diodes

“…However, the large contact resistance of carbon nanotubes limits the conductivity of the flexible transparent electrodes (FTEs) prepared with them [8,9]. Graphene is a material with high light transmittance, high electrical conductivity, and excellent flexibility, but its high cost makes it difficult to achieve the large-scale industrial production of graphene FTEs [10,11]. Conductive polymers, especially poly (3,4-ethylenedioxythiophene): poly (styrenesulfonate) (PEDOT: PSS), have high transmittance, high mechanical flexibility, and excellent thermal stability in the visible light range [12,13].…”

The antimicrobial efficacy of nanographene oxide and double antibiotic paste per se and in combination: part II

“…Carbon-based nanomaterials encompass a variety of allotropic forms of carbon nanostructures such as graphene and carbon nanotubes [ 4 ]. Graphene is a two-dimensional single layer of carbon atoms that are covalently bonded in a hexagonal honeycomb lattice [ 5 – 7 ]. It serves as a fundamental building block of carbon materials of different dimensionalities including zero-dimensional buckyball and graphene quantum dot, one-dimensional carbon nanotube, and three-dimensional graphite [ 7 , 8 ].…”
