mechanical properties of graphene

Moreover, the development of lightweight materials especially for an automotive vehicle is the most highlighted area of today’s research. [99] reported that with the incorporation of 0.3 wt% graphene, the tensile strength and storage modulus of nanocomposites increased from 57.2 to 64.4 MPa and 1.66 to 2.16 GPa, respectively. [14] reported that the CNT/PP nanocomposite typically exhibit superior tensile strength and better thermal conductivity as compared to the GNP/CNT nanocomposites and GNP/CNT/PP hybrids.

[82] monitored the effect of epoxide cure kinetics by keeping the cross-linking mechanism under observations through the use of DSC. Chemical functionalization and specific contact area based techniques have been employed to assess the reduction in the size of the particle fillers.

The results of this study indicated that the incorporation of 0.10 wt% of GO into EP enhanced the ILSS by 8.05%, with an increase in Tg by 5 °C. [136] incorporated GO into epoxy matrix to observe that the Tg of nanocomposites enhanced by 33.05 °C with the 1.0 wt% fraction of filler.

The thermal conductivity determined by considering the orientation and properties of fillers, the morphology of the polymer nanocomposites, and their interaction with the fillers and the epoxy matrices is depicted in Fig. It is inferred from the experiment that in situ polymerization accelerates a better dispersion of GO in the polymer matrix. This is due to homogeneous distribution of fillers and improved load transfer capability between hydrogen bond contained by modifier and matrix. The various factors pertaining to thermal properties at different filler contents of graphene- and modified graphene-reinforced epoxy nanocomposites are listed in Table 3.

The high aspect ratio and van der Walls interactions of graphene and its agglomerates have been used widely so that decoration of graphene with other nanofillers can be deployed in order to avoid this phenomenon.
