“…39 However, when an electric eld is applied, the ER uids begin to transform toward a "elastic solid", and the shear stress increases as the electric eld strength increases, which presents the performance of Bingham uid-like behavior. [40][41][42][43][44] Because of the formation of the chain-like structure between the dispersed MIL-125@PANI particles, ER uids exhibited a strong ow resistance. As we can see in Fig.…”

“…With the addition of GO to pPDA, there was a p-p stacking interaction between GO and pPDA. 30 A redox reaction was responsible for the covalent functionalization of pPDA with GO 19 through amide-bond formation. The carboxylic group in GO was reduced, and one of the two primary amine groups in the pPDA molecule was oxidized.…”

ABSTRACT:In an attempt to enhance the mechanical properties of epoxy/graphene-based composites, the interface was engineered through the functionalization of graphene oxide (GO) sheets with p-phenylenediamine; this resulted in p-phenylenediamine functionalized graphene oxide (GO-pPDA). The morphology and chemical structure of the GO-pPDA sheets were studied by spectroscopic methods, thermal analysis, X-ray diffraction, and transmission electron microscopy. The characterization results show the successful covalent functionalization of GO sheets through the formation of amide bonds. In addition, p-phenylenediamine were polymerized on graphene sheets to form crystalline nanospheres; this resulted in a GO/poly(p-phenylenediamine) hybrid. The mechanical properties of the epoxy/ GO-pPDA composite were assessed. Although the Young's modulus showed improvement, more significant improvements were observed in the strength, fracture strain, and plane-strain fracture toughness. These improvements were attributed to the unique microstructure and strong interface between GO-pPDA and the epoxy matrix.

“…Cao et al [148] also utilized the ball milling method to exfoliate graphite with dry ice for 48 h in the presence of carbon dioxide to produced graphene oxide nanoplatelets (GONPs) that were later combined with poly(p-phenylenediamine) to produce the composites. The resulting GONPs showed a high specific surface area of 589.7 m 2 g -1 .…”

Graphene is a new and exciting material that has attracted much attention in the last decade and is being extensively explored because of its properties, which have been described with so many superlatives. Production of graphene for large scale application is still a major challenge. Top-down graphene exfoliation methods from graphite, such as liquid-phase exfoliation which is promising because of low cost and high scalability potential will be briefly discussed. We also analyze the challenges and possibilities of using graphene as a nanofiller in polymer composites which has resulted in enhanced electrical, mechanical and thermal properties. In this review, we take a panoramic approach to give insight on the different aspects of graphene such as properties, graphite-based production methods and also examples of graphene application in polymer composites and will be beneficial to both novice and experts.
