Опубликована: Июль 21, 2017

In this present review, the current status of intrinsic mechanical properties graphene-family materials along with preparation and bulk graphene-based nanocomposites is thoroughly examined. The usefulness Raman spectroscopy for characterization study graphene flakes their composites clearly exhibited. Furthermore, strategies are discussed reported in literature analysed. particular, through analyse several hundred papers on composites, we have found a unique correlation between filler modulus, derived from rule mixtures, composite matrix. This to hold true across wide range polymer matrices thus suggests that common assumption modulus independent matric incorrect, explaining apparent under performance some systems. presence even at very low loadings can provide significant reinforcement final material, while parameters affect nanocomposite strongly reviewed. Finally, potential applications future perspectives regard scale up capabilities possible developments materials.

Synthesis of Graphene Oxide using Modified Hummers Method: Solvent Influence

Procedia Engineering, Год журнала: 2017, Номер 184, С. 469 - 477

Опубликована: Янв. 1, 2017

The aim of this study is to the influence different solvents on structure and electrical properties graphene oxide. GO was obtained from graphite flakes by using modified hummers method in which conventional hummer's method. In method, experiment synthesized without sodium nitrate (NaNO3) ice bath, but carried out at room temperature. Prepared powders were then dissolved into solvents, namely acetone ethanol. Then spin-coated onto silicon wafer IDE produce acetone-GO (A-GO) ethanol-GO (E-GO). SEM result shows that several square micron obtained. addition, due large agglomerates contact between E-GO sample, current-voltage pattern indicated produced higher current flow than A-GO. Meanwhile, characterized FTiR both samples contain functional groups such as hydroxyl, epoxy, carboxyl carbonyl. Besides that, lower diffraction peak A-GO, XRD interlayer spacing A-GO sample slightly sample.

Carbon-based structures are the most versatile materials used in modern field of renewable energy (i.e., both generation and storage) environmental science (e.g., purification/remediation). However, there is a need indeed desire to develop increasingly more sustainable variants classical carbon activated carbons, nanotubes, aerogels, etc.), particularly when whole life cycle considered from precursor "cradle" "green" manufacturing product end-of-life "grave"). In this regard, perhaps mimicking some respects natural cycles/production, utilization natural, abundant precursors, coupled with simpler, lower synthetic processes which can contribute part reduction greenhouse gas emissions or use toxic elements, be as crucial parameters development manufacturing. Therefore, synthesis application receiving increasing levels interest, benefits context future energy/chemical industry becoming recognized.
