This work represents a state-of-the-art technique developed for the preparation of graphene from graphite-metal electrodes by the arc-discharge method carried out in a continuous flow of water. Because of continuous arcing of graphite-metal electrodes, the graphene sheets were observed in water with uniformity and little damage. These nanosheets were subjected to various purification steps such as acid treatment, oxidation, water washing, centrifugation, and drying. The pure graphene sheets were analyzed using Raman spectrophotometry, x-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM), and tunneling electron microscopy (TEM). Peaks of Raman spectra were recorded at (1300-1400 cm À1 ) and (1500-1600 cm À1 ) for weak D-band and strong G-band, respectively. The XRD pattern showed 85.6% crystallinity of pure graphite, whereas pure graphene was 66.4% crystalline. TEM and FE-SEM micrographs revealed that graphene sheets were overlapped to each other and layer-by-layer formation was also observed. Beside this research work, we also reviewed recent developments of graphene and related nanomaterials along with their preparations, properties, functionalizations, and potential applications.

Nano‐polystyrene (nPS)‐decorated graphene oxide (GO) hybrid nanostructures were successfully synthesized using stepwise microemulsion polymerization, and characterized using Fourier transform infrared (FTIR) spectroscopy, X‐ray diffraction (XRD), field‐emission scanning electron microscopy and transmission electron microscopy. XRD and FTIR spectra revealed the existence of a strong interaction between nPS and GO, which implied that the polymer chains were successfully grafted onto the surface of the GO. The nPS‐decorated GO hybrid nanostructures were compounded with epoxy using a hand lay‐up technique, and the effect of the nPS‐decorated GO on the mechanical, thermal and surface morphological properties of the epoxy matrix was investigated using a universal tensile machine, Izod impact tester, thermogravimetric analysis and contact angle measurements with a goniometer. It was observed that in the epoxy matrix, GO improved the compatibility. © 2017 Society of Chemical Industry

Five kinds of organic rectorite (OREC)-reinforced Epoxy Resin (EP) composites (OREC/EP) were prepared by using different ORECs as modifiers. The curing process of EP, the functional groups of OREC and its interlayer distance (d-spacing) are demonstrated by Fourier Transform Infrared Radiation (FTIR) and XRD (X-Ray Diffraction). The morphologies of OREC/EP composites and the dispersion of OREC in the cured EP matrix were investigated using XRD and scanning electron microscopy (SEM). The mechanical properties, thermal deformed temperature (HDT), hot-wet resistance, alkali resistance and water adsorption of the resulting OREC/EP composites were evaluated. It is found that the addition of OREC can improve the comprehensive properties of EP. The maximum mechanical properties of OREC/EP can be obtained by OREC3/EMI-2, 4/E-51 due to the high stiffness and uniform dispersion of OREC in matrixes. The most desirable properties of OREC/EP composites were obtained with impact strength of 9.5 kJ/m 2 , bent strength of 86 KPa and HDT of 182 C, all of which is improved by 8.0%, 8.9% and 28.2% than those of pure EP, respectively. INTRODUCTIONEpoxy resin (EP) has been used in many fields because of its cheapness and wide practicality [1][2][3][4][5] . However, its lower impact strength and weak hot wet-resistance strength limit its extensive applications. Many researchers are working on the aspect of improving the impact and hot resistance properties of EP [6][7][8] . In recent years, polymer= layered silicate nano-composites have attracted considerable interest because they possesses the structure, physical, and chemical properties of both inorganic and organic materials [9][10][11][12] .Most work on polymer=layered silicate nanocomposites has focused on montmorillonite (MMT), hectorite, and saponite modifications, and so on [10][11][12][13][14][15][16] .Rectorite (REC) with structure and characteristics similar to montmorillonite might be preferred for layered silicates because of its cheapness. It is a type of regularly interstratified clay mineral with alternate pairs of dioctahedral mica-like layer (nonexpansible) and dioctahedral montmorillonite-like layer (expansible) in a 1:1 ratio. The separable layer thickness and layer aspect ratio (area thickness) of REC are larger than those of regular montmorillonite.These characteristics may be favorable for forming the intercalated or exfoliated nano-composites, and help to improve the efficiency of reinforcement of nano-layers in many properties [17][18][19][20][21] . Although several types of polymer=layered silicate nano-composite products with different shapes and applications-including food packaging films and containers, engine parts, dental materials, etc.-are now available in markets, polymer=layered silicate nano-composites with antimicrobial activity, which appear very favorable to the applications of nano-composites, are rarely explored.Based on previous works, organic rectorite (OREC) was prepared by means of a cation exchange mechanism in this work. Then, different k...
