“…Figure 2 shows Gr is a high-strength, two-dimensional material with high electrical and thermal conductivities. After being composited with inorganic materials or polymers, Gr composites are generally classified into the following two categories: Gr/inorganic and Gr/polymer composite materials [31,32]. Composite materials have been widely used in photoelectric conversion materials, catalysts, structure-reinforcing materials, adhesives, functional film materials, and biomedical materials, among others.…”

As two-dimensional materials with a high specific surface area, strength, and electrical and thermal conductivity, graphene (Gr) and its derivatives have great application prospects in various fields such as structural reinforcement, energy storage, optics, and electrical and thermal conductivity. However, the current preparation method of Gr is complicated and expensive. Its preparation cost can be reduced using Gr composites that include inorganic materials or other polymers. Composite materials comprising Gr and inorganic materials are generally prepared using sinter molding, chemical reduction, or chemical deposition. Gr should be able to mitigate several of the defects resulting from inorganic materials, including their poor toughness, small specific capacity, and low photoelectric conversion rate. The mitigation of these defects should result in the expansion of the applications of Gr composites for use in capacitors, catalysts, and sensors, among other devices. Although solution blending or in situ polymerization produces a relatively good mixing effect, in general, melt blending is used in the large-scale processing of Gr composites with polymer materials. Gr can be used to partially mitigate several weaknesses of polymer materials, including their low strength, poor electrical and thermal conductivities, and poor isolation performance, and expand the applications of Gr composites for use in electrical and thermal conductive materials and functional membrane materials, among other applications. The goal of the present paper is to introduce the structural properties of Gr and a surface modification method for Gr. In addition, the preparation methods and application fields of different Gr composite materials are reviewed. Finally, the development prospects and key issues are discussed.

“…An ideal association of materials to form composite systems may offer a solution to overcome the limitations of MOFs, such as water sensitivity or mechanical weakness [ 19 , 20 , 21 ]. Graphene and graphene derivatives are excellent candidates for associates, since it is proved that in hybrid systems, they can improve water resistance, as well as electrical, thermal and mechanical properties [ 22 , 23 ]. Graphene, ideally, is a single sheet of graphite with a honeycomb-like lattice structure.…”

Graphene Oxide Protected Copper Benzene-1,3,5-Tricarboxylate for Clean Energy Gas Adsorption

Among microporous storage materials copper benzene-1,3,5-tricarboxylate (CuBTC MOF, Cu3(BTC)2 or HKUST-1) holds the greatest potential for clean energy gases. However, its usefulness is challenged by water vapor, either in the gas to be stored or in the environment. To determine the protection potential of graphene oxide (GO) HKUST-1@GO composites containing 0–25% GO were synthesized and studied. In the highest concentration, GO was found to strongly affect HKUST-1 crystal growth in solvothermal conditions by increasing the pH of the reaction mixture. Otherwise, the GO content had practically no influence on the H2, CH4 and CO2 storage capacities, which were very similar to those from the findings of other groups. The water vapor resistance of a selected composite was compared to that of HKUST-1. Powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric (TG/DTG) and N2 adsorption techniques were used to monitor the changes in the crystal and pore structure. It was found that GO saves the copper–carboxyl coordination bonds by sacrificing the ester groups, formed during the solvothermal synthesis, between ethanol and the carboxyl groups on the GO sheets.

“…Graphene (G) and its family members including graphene oxide (GO) and reduced graphene oxide (rGO) had many special properties, such as physical barrier, chemical, mechanical, electrochemical, and thermal properties, which had attached great importance to researchers and industrial engineers in the fields of metal corrosion protection, antifouling, and other functional coatings . Anti‐corrosion of coatings regarding graphene/graphene‐derivative had become one of the most popular research areas .…”

A comb copolymer (CC) is designed and prepared in present article, by grafting epoxy resin (E-20) on poly(styrene-co-acrylate). The CC is used as a special dispersant, which leads to a stabilizable reduced graphene oxide (rGO) suspension in organic coatings. The dispersing mechanism is deduced as π-π attraction between CC and rGO, which is supported by the analysis data of Fourier transform infrared (FTIR) spectra, Raman spectroscopy, scanning electron microscope, transmission electron microscope, and X-ray photoelectron spectroscopy. The corrosion resistance of CG suspension is determined by electrochemical impedance spectroscopy, the results implies that the anti-corrosion behavior performed obviously, and protective efficiency is up to 99.53% in Tafel analysis.
