This work recommends an optimum content of rGO required for effective improvement in thermomechanical properties of rGO/ABS composites. According to electrical conductivity measurements, the percolation threshold of rGO in ABS should be around 1 wt% but mechanical and rheological properties keep on increasing beyond this value. However, on the basis of tensile and damping properties, 1.5 wt% is the optimum content of rGO that should be used as reinforcement in thermoplastic polymer matrices. Composites having 1.5 wt% rGO in ABS have shown significant improvement in tensile strength, excellent degree of entanglement (specially at higher temperatures) and a very low value for C-factor. As observed in FESEM micrographs, the deterioration of properties with further increase in rGO content (2 wt% and above) should be due to non-uniform dispersion of filler inside the matrix. Moreover, the elliptical shape of Cole-Cole plots validates the compatibility of rGO as reinforcing filler in ABS matrix.
