“…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]. Chang et al [93] applied polyaniline/graphene composites (PAGCs) for corrosion inhibition of steel. The composites display outstanding barrier properties against O 2 and H 2 O.…”

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.

“…Combining the unique properties of graphene and polyaniline, graphene/polyaniline composites are a new class of performing materials that have attracted much attention of researchers in the last years due to the synergistic effects on their thermal, electronic and mechanical properties [13][14][15]. They have been developed and investigated for use mainly as high-performance supercapacitor electrode materials [16], microwave shielding [17], corrosion protection [18] or counter-electrode for dye-sensitized solar cells [19]. The performances of graphene/PANI composites are strongly dependent on the interfacial interactions between partners providing a blending to molecular level, without segregation during synthesis and operation.…”

Abstract. Three water-dispersable composites have been synthesized by in situ chemical oxidative polymerization of aniline N-propanesulfonic acid (AnS) in reduced graphene oxide (r-GO) dispersion, in an ice bath at 0°C and in the absence of any surfactant. The mass ratio between r-GO and aniline monomer have been established as (m r-GO :m AnS ) = 1:1, 1:2 and 1:5 while in the composites, the mass ratio between r-GO and polyaniline was found: 1:0.3, 1:0.5 and 1:1, respectively. The molecular structure, morphology, and optical properties of the composites were analyzed through Fourier transform infrared (FTIR), Raman and ultraviolet-visible (UV-Vis) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). Electrochemical performances for energy storage were evaluated by cyclic voltammetry and galvanostatic charge/discharge measurements with 1M H 2 SO 4 as electrolyte in a three-electrode cell. The composite with the mass ratio (m r-GO :m PAnS ) = 1:1 has showed good capacitive behavior with a specific capacitance of 1019 F/g at scan rate of 1 mV/s calculated from integrated area of cyclic voltammogram curve and a retention life of 80% after 100 cycles. These results indicate that the composites prepared by chemical oxidative polymerization are promising materials for electrode supercapacitors.

“…They showed that the incorporation of a small number of nanoparticles-especially Fe 2 O 3 and halloysite clay-into the epoxy coating can enhance the corrosion resistance of the epoxy-coated steel. In recent years, it was reported that carbon derivatives, such as carbon nanotubes (CNTs) [16][17][18], graphene (Gr) and graphene oxide (GO) [19][20][21][22][23][24][25][26][27][28][29][30][31] can be used as anti-corrosion additives to organic coatings. Gr has attracted considerable attention owing to its extraordinary electrical and physical properties, especially its impermeable nature [32][33][34].…”

Abstract:This work contributes to the development and characterization of the corrosion resistance and antifriction properties of high performance polyurethane (PU)/graphene (Gr) composite coating. In this study, PU composite coatings containing 0, 2, 4 and 8 wt.% of Gr were prepared and evaluated using various corrosion and mechanical tests, namely electrochemical impedance spectroscopy, salt spray tests, cross-cut tape tests and dynamic mechanical analysis. Antifriction properties of the coatings were evaluated using a tribometer with a ball-on-disc mode at room temperature. The corrosion resistance and adhesion property of the PU coatings were found to be enhanced by adding 4 and 8 wt.% of Gr. The coefficient of friction revealed that the antifriction properties of the PU/Gr composite coatings were 61% lower than those of the conventional coating when the Gr content was increased to 8 wt.%.
