“…In this regard, N-and S-contained functional groups, such as amine and sulfonate, are frequently used to modulate the surface chemical characteristics of Gn nanomaterial. 105 The incorporation of such functional groups has been demonstrated in several studies to play a role in controlling the morphology of PANI nanostructures anchored on the Gn plane. In this section, the preparation and performance of several functionalized-Gn/PANI hybrid electrodes are summarized and discussed, along with the critical factors that influence the electrocapacitive properties of the resultant hybrid electrodes.…”

The high demand for efficient energy devices leads to the rapid development of energy storage systems with excellent electrochemical properties, such as long life cycles, high cycling stability, and high power density. SC is postulated as a potential candidate to fulfill this demand. The combination of graphene and polyaniline can create SC electrodes with excellent electrical conductivity, high specific surface area, and high capacitance. The graphene/polyaniline hybrid electrodes represent an attractive means to overcome the major drawbacks of graphene or polyaniline non-hybrid (single) electrode materials. In this review article, the trend in the development of various graphene/polyaniline hybrid electrodes is summarized, which includes the zero-dimension graphene-quantum-dots/polyaniline hybrid, one-dimension graphene/polyaniline hybrid, two-dimension graphene/polyaniline hybrid, and three-dimension hydrogel-shaped graphene/polyaniline hybrid. Several strategies and approaches to enhance the capacitance value and cycling stability of graphene/polyaniline hybrid electrodes are discussed in this review article, such as the addition of transition metal oxides and metal-organic frameworks, and modification of graphene into functionalized-graphene. The performance of the electrodes prepared from the combination of graphene with other conducting polymers (i.e., polypyrrole, polythiophene, and polythiophene-derivatives) is also discussed.

“…PANi has fast charge-discharge kinetics and doping-undoping processes. In this concern, PANi is one of the most studied conducting polymers for making composite with graphene for supercapacitors (Hong et al 2019). In-situ polymerization of aniline (monomer of PANi) on GO surface results uniform coverage of PANi on the converted rGO or CCG (derived from GO), which provides improved electrical conductivity as well as high specific capacitance compares to pristine PANi.…”

Recently, many researchers are highly motivated on a wide range of 2D materials such as boron nitride, graphite carbon nitride, and black phosphorus due to their favorable physicochemical properties that lead to their diverse applications in potential fields including photocatalysis, energy storage, biomedical applications, etc. The pioneer of this research related to 2D materials is of course graphene. Nowadays, researchers are using graphene and its compounds such as graphene oxide, reduced graphene oxide, and chemically converted graphene (also called chemically modified graphene) to make graphene-based functional nanocomposites as go-to materials for large-scale industrial as well as clinical applications. This chapter is mainly dedicated towards modern synthesis techniques with the key properties of graphene-based nanocomposites, their vast array of applications, and finally, illustration of the future prospect of the wonderful nanocomposite materials.

“…However, as a nanomaterial, especially in the powder form, graphene can cause a serious health hazard through pulmonary, oral or dermal exposure, where inhalation causes the greatest risk [6][7][8][9]. What is more, depending on the production method, graphene may strongly influence environmental safety (e.g., graphene oxide production requires strong, concentrated acids that generate hazardous waste which must be disposed of [10]).…”

Quasi-Monocrystalline Graphene Crystallization on Liquid Copper Matrix

et al. 2020

To access the properties of theoretical graphene, it is crucial to manufacture layers with a defect-free structure. The imperfections of the structure are the cause of deterioration in both electrical and mechanical properties. Among the most commonly occurring crystalline defects, there are grain boundaries and overlapping zones. Hence, perfect graphene shall be monocrystalline, which is difficult and expensive to obtain. An alternative to monocrystalline structure is a quasi-monocrystalline graphene with low angle-type boundaries without the local overlapping of neighboring flakes. The purpose of this work was to identify factors that directly affect the structure of graphene grown on a surface of a liquid metal. In the article the growth of graphene on a liquid copper is presented. Nucleating graphene flakes are able to move with three degrees of freedom creating low-angle type boundaries when they attach to one another. The structure of graphene grown with the use of this method is almost free of overlapping zones. In addition, the article presents the influence of impurities on the amount of crystallization nuclei formed, and thus the possibility to order the structure, creating a quasi-monocrystalline layer.
