The addition of 0.9 wt% graphene into polystyrene resulting in 57.2 and 69.5% increase in Young’s modulus and
tensile strength, respectively, as reported by Fang et al. (2009). Yang et al. (2010) studied the uniform dispersion
of 1 wt% GO in chitosan matrix successfully increased tensile strength and Young’s modulus by 122 and 64%,
respectively. Ganguli et al. (2008) observed reinforcing effect of 4% graphite in epoxy resin, increasing Tg value from 155 to 175ºC (Ganguli et al. 2008)
