“…Graphene and graphene derivatives (e.g., graphene/graphite oxide, functionalized graphene, etc.) could be used in various applications such as hydrogen storage [82], sensors [83], transparent conductive films [84], batteries [85,86], super capacitors [87], solar cells [88] and nanocomposites coatings [89][90][91]. Due to the high surface area of graphene sheet (2630 m 2 /g), improvement of mechanical, thermal, and electrical properties of composite graphene based coating could be achieved with very low loading [92].…”

Abstract:Corrosion is a deterioration of a metal due to reaction with environment. The use of corrosion inhibitors is one of the most effective ways of protecting metal surfaces against corrosion. Their effectiveness is related to the chemical composition, their molecular structures and affinities for adsorption on the metal surface. This review focuses on the potential of ionic liquid, polyionic liquid (PIL) and graphene as promising corrosion inhibitors in emerging coatings due to their remarkable properties and various embedment or fabrication strategies. The review begins with a precise description of the synthesis, characterization and structure-property-performance relationship of such inhibitors for anti-corrosion coatings. It establishes a platform for the formation of new generation of PIL based coatings and shows that PIL corrosion inhibitors with various heteroatoms in different form can be employed for corrosion protection with higher barrier properties and protection of metal surface. However, such study is still in its infancy and there is significant scope to further develop new structures of PIL based corrosion inhibitors and coatings and study their behaviour in protection of metals. Besides, it is identified that the combination of ionic liquid, PIL and graphene could possibly contribute to the development of the ultimate corrosion inhibitor based coating.

Facile synthesis and application of Ag-chemically converted graphene nanocomposite

An in situ chemical synthesis approach has been employed to prepare an Ag-chemically converted graphene (CCG) nanocomposite. The reduction of graphene oxide sheets was accompanied by generation of Ag nanoparticles. The structure and composition of the nanocomposites were confirmed by means of transmission electron microscopy (TEM), atomic force microscopy (AFM) and X-ray diffraction. TEM and AFM results suggest a homogeneous distribution of Ag nanoparticles (5-10 nm in size) on CCG sheets. The intensities of the Raman signals of CCG in such nanocomposites are greatly increased by the attached silver nanoparticles, i.e., there is surface-enhanced Raman scattering activity. In addition, it was found that the antibacterial activity of free Ag nanoparticles is retained in the nanocomposites, which suggests they can be used as graphene-based biomaterials.

“…Owing to random distribution of functional groups such as oxygen, hydroxyl, carbonyl and epoxy, it has a wide variety of applications like in electronic transistors, transparent conducting films, light-emitting devices and solar cells, etc. [3][4][5][6][7][8][9][10][11]. The properties of GO are highly dependent on the oxidation state and hydroxyl groups attached [12].…”

Graphene oxide (GO) is a biocompatible material that is easily dispersible in water making its mixing easy with ceramic or polymer matrixes while trying to enhance their properties. In the present study, the photocatalytic and antibacterial activities of GO have been studied. GO has been synthesized by modified Hummer's method. The synthesized material has been characterized using X-ray diffraction, Raman spectroscopy, high-resolution transmission electron microscopy (HR-TEM), Fourier transform infrared spectroscopy (FT-IR) and UV-visible spectroscopy. HR-TEM confirmed the formation of GO nanosheets. It has been observed that GO nanosheets with excellent morphology exhibit efficient photocatalytic activity towards Congo red (CR) dye. Using advanced oxidation process, toxic organic dye CR is oxidized through reaction with reactive oxidative species generated by GO photocatalyst under UV-light irradiation. The study reflects new possibilities of GO for degradation of toxic organic pollutants. The effect of GO dose has also been studied and the reaction has been evaluated to be first order. Antibacterial activity of GO has been evaluated via well diffusion assay by growing Escherichia coli and Bacillus on LB agar plates.
