摘要

This work enlightens the effect of three different derivatives of graphene on mechanical, thermal and rheological properties of acrylonitrile-butadiene-styrene (ABS) composites prepared via melt-mixing technique. These nanofillers i.e. graphene oxide (GO), chemically reduced graphene oxide (rGO-C) and thermally reduced graphene oxide (rGO-Th), with selective low percolation threshold in ABS, brought erratic outcome. It has been noticed that rGO-C acts as better reinforcement in ABS than other derivatives. Improvement in tensile strength by 1.8-fold, storage modulus by 12% and glass transition by 11 degrees C has been achieved with rGO-C/ABS composites. Some typical secondary correlations based on dynamic storage modulus i.e. variations in stiffness, degree of entanglement and C-factor, have been used to exaggerate the change in dynamic properties more precisely. Creep and recovery behaviour, investigated at different environment temperatures and three different stress levels, also shown minimum creep deformation and superior recovery using rGO-C.
