“…For example, for epoxy nanocomposites, FGS are fi rst dispersed in the monomer with help of a solvent, and high shear mixing and polymerization is performed after solvent removal. [ 61 ] The comparison among the mechanical properties obtained from these three main methods or a combination of them, is diffi cult because of the differences between the systems studied. There are various factors that affect the dispersion degree of the nanofi ller and, consequently, the fi nal properties of the material.…”

Graphene constitutes a two dimensional sp2 hybridized carbon material with outstanding electrical and mechanical properties. To date, novel methods for producing large quantities of graphene and its derivatives (doped or functionalized graphenes, nanoribbons and nanoplatelets) are emerging, and research dedicated to the fabrication of polymer nanocomposites using graphenes has started. In this Research News, we summarize the synthesis and properties of graphene and its derivatives, and provide an overview of the latest research dedicated to the fabrication of polymer composites for different applications, including mechanical, electrical, optical and thermal. Some of the recently fabricated composites exhibit outstanding properties, however, it is vital to understand the chemistry and physics of the interphases established between the polymer and the graphene surfaces. The challenges in the fabrication of super robust and highly conducting composites using graphenes are also discussed. It is believed that graphene‐based polymer composites will result in commercial products if their interphases and reactivity are carefully controlled.

“…In situ polymerization is considered to be a very efficient method dispersing nanomaterials into the polymer matrix [84,85]. Through in situ polymerization, GO or graphene nanosheets have been successfully incorporated into many kinds of polymer matrix, such as poly (methyl methacrylate) [86,87], epoxy [88], and thermoplastic polyurethanes [80]. The mechanical, thermal, and electrical properties of polymer matrix can be significantly improved through the judicious addition of graphene-based additives.…”

Abstract:Graphene, as an intermediate phase between fullerene and carbon nanotube, has aroused much interests among the scientific community due to its outstanding electronic, mechanical, and thermal properties. With excellent electrical conductivity of 6000 S/cm, which is independent on chirality, graphene is a promising material for high-performance nanoelectronics, transparent conductor, as well as polymer composites. On account of its Young's Modulus of 1 TPa and ultimate strength of 130 GPa, isolated graphene sheet is considered to be among the strongest materials ever measured. Comparable with the single-walled carbon nanotube bundle, graphene has a thermal conductivity of 5000 W/(m·K), which suggests a potential application of graphene in polymer matrix for improving thermal properties of the graphene/polymer composite. Furthermore, graphene exhibits a very high surface area, up to a value of 2630 m 2 /g. All of these outstanding properties suggest a wide application for this nanometer-thick, two-dimensional carbon material. This review article presents an overview of the significant advancement in graphene research: preparation, functionalization as well as the properties of graphene will be discussed. In addition, the feasibility and potential applications of graphene in areas, such as sensors, nanoelectronics and nanocomposites materials, will also be reviewed.

“…[ [5][6][7][8][9][10] To obtain defect-free, high-quality graphene sheets, the most widely used approaches are chemical vapour deposition [11,12] and micromechanical cleavage of graphite [13]. Still, these approaches show a low production yield and are time consuming.…”
