Grafting of epoxy chains onto graphene oxide for epoxy composites with improved mechanical and thermal properties

Recently, graphene has attracted both academic and industrial interest because it can produce a dramatic improvement in properties at low filler content. The utilization of graphene-based materials in the fabrication of nanocomposities with different polymer matrixes has been explored. This review article presents and discusses the development of graphene-based polymer composites and their applications in different fields such as electronics devices, energy storage, sensors, ESD and EMI shielding and biomedical applications.

Graphene-Based Polymer Composites and Their Applications

In the present review, the recent progress in describing the intricacies of mechanical and thermal properties of all types of graphene- and modified graphene-based polymer nanocomposites has been comprehensively examined. The effectiveness of microscopy bouquet for the intrinsic characterization of graphene family and their composites was clearly demonstrated in this research. Furthermore, the utility of the dynamic mechanical analysis and thermo-gravimetric analysis employed for thermal characterization that has been reported by various researchers was exhaustively analyzed in this paper. This research primarily focused on the analyses of several good articles concerned with hybrid graphene composites and the synergetic effect of graphene with other nanofiller to assess its effect on the mechanical properties of its corresponding composites. Such systematic analysis of previous literatures imparted a direction to the researchers about the solution of improved interfacial properties as well as the enhanced dispersion into the vicinity of the matrix. This current research has suggested that the presence of the graphene filler even at very low loadings has shown considerable improvement in the overall mechanical properties of graphene. Further studies to optimize the value of the filler need to be addressed in order to gain complete understanding of the properties of graphene. The potential applications, current challenges, and future perspectives pertaining to these nanocomposites were elaborately discussed in the current study with regard to the multi-scale capabilities and promising developments of the graphene-family-based nanocomposites materials.

Significantly modified tribological performance of epoxy nanocomposites at very low graphene oxide content

A facile approach to fabricate graphene oxide (GO) reinforced epoxy resin nanocomposites was developed by transferring GO from water to acetone. Three-point bending test, impact test, dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA) were used to investigate the mechanical and thermal properties of the nanocomposites. The results showed that significant improvements in flexural strength, flexural modulus, impact strength, and storage modulus were achieved when incorporating ∼1 wt% of graphene oxide. The TGA analysis indicated that the introduction of GO has not demonstrated obvious effect on the thermal stability.
