“…Thus, various methods have been developed to exfoliate graphite and stabilize graphene sheets [7][8][9]. Among these strategies are included top down approaches: a) micromechanical cleavage of graphite [10][11], b) unzipping of carbon nanotubes [12][13][14], c) liquid-phase exfoliation [15][16][17], d) exfoliation and reduction of graphite oxide [18][19][20][21], bottom-up chemical synthesis of polycyclic aromatic hydrocarbons [22][23] as well as chemical vapor deposition synthesis of graphenes [24][25][26].…”

“…The elimination of carboxyl and epoxy group also occured during thermal reduction of graphene oxide [5].The different applied pressures during spray process are one of the factors that affect the uniformity of RGO on the substrate. From the result, the surface of the RGO becomes wrinkled and shrinks [12]. …”

The biosensor platform of graphene material has grown rapidly in the past few years due to their unique properties in electrical, thermal conductivity, large surface area, high fracture strength, high young modulus and biocompatibility. In this work, the chemically modified graphene oxide solutions were studied for electrical performance toward biosensor applications. The graphene oxide solutions were sprayed manually on top of silicon substrate at various temperatures of 100, 200 and 300 °C, respectively. Out of those temperatures, at 100 °C, the surface morphology of reduction graphene oxide showed a better performance in electrical measurement. Atomic Force Microscopy (AFM) and Scanning Electron Microscopy were carried out to investigate the thermal reduction and the formation of graphene through surface morphology observation. Then a surface modification will conducted using APTES and electrical characteristic of the current-voltage (i-v) were performed.

“…For example, exfoliation of graphene sheets was carried out in the aqueous solutions of alkaline lignin [22], sodium dodecyl sulfate [29], and sodium dodecylbenzene sulfonate [13], as well as in organic solutions of imidazole [30], 1-pyrenecarboxylic acid [31], dimethylformamide [32], mixture of benzene and hexafluorobenzene [16], or heptane [33], as well as the products of polymerization of styrene and divinylbenzene [34].…”

In this study, the syntheses of oxygen-free graphene sheets and the method of its fixation at an oil-aqua interface were presented. e graphene sheets were prepared by exfoliation of synthetic graphite powder in an aqua-organic medium under ultrasound irradiation. N,N-Dimethyloctylamine-(DMOA-) aqua emulsion was used as the liquid medium, and pH was equal to 3. e obtained graphene nanosuspension was fractionated by sedimentation and decanted according to the weight. e graphene nanoparticle fractions, differing in configuration and number of layers, have been characterized using transmission electron microscopy (TEM), electron diffraction, HRTEM, Raman spectroscopy, and electron energy loss spectroscopy (EELS). It was found that using a DMOA-aqua mixture as the liquid medium in ultrasonic treatment of synthetic graphite leads to the formation of oxygen-free 1-2-layer graphene sheets attached to the DMOA-aqua interface. e proposed method differs from known ones by using a small amount of more environmentally friendly organic substances. It allows to obtain large quantities of oxygen-free graphene, and finally unconverted graphite can be directed for reuse. e proposed method allows to obtain both 2D graphene sheets with micron linear dimensions and 3D packages with a high content of defects. Both these species are in demand in areas related to the development of new materials with unique electrophysical properties.
