Epoxy/multi-layer graphene nanocomposites prepared with different acetone dosages (0 ml, 25 ml and 50 ml) were successfully produced. This study investigates the effectiveness of short-term dispersion and small dosages of acetone on the properties of nanocomposites. The maximum increase in glass transition temperature (Tg), storage modulus, flexural strength, flexural modulus, fracture toughness and microhardness were observed in the case of epoxy/0.1 wt % MLG dispersed in an epoxy matrix. Scanning Electron Microscopy (SEM) analysis revealed that a good dispersion of MLG in the epoxy matrix has the ability to prevent and stop crack propagation. The cracks became parabolic or emanated radially in comparison to monolithic epoxy samples. For samples prepared with acetone, smooth surfaces can be seen on the fractured samples due to retained acetone that acts as stress raisers, which result in straight crack propagation and consequently reduced mechanical properties of the nanocomposites.
