Das et al. (2009) employed the nanoindentation technique to the graphene-reinforced nanocomposite fabricated by using polyvinyl alcohol (PVA) and PMMM. The results showed significant improvement in crystallinity, elastic modulus, and hardness through the addition of only 0.06 wt% of graphene. The authors suggested that the enhancement was due to close mechanical interaction between the host (polymer) matrix and the layers of graphene. This interaction successively provides and dictates a better load transfer within the host matrix and the nanofiller [112]. Yu et al. (2007) identified that epoxy-based few-layer graphene nanocomposites show fascinating properties for the electronics industry, ideal for development of thermal-interface-based materials [113].
