1. Introduction Acrylonitrile butadiene styrene (ABS) terpolymer containing CF is one of the potential materials to become an industrial solution to achieve demanded limits for these properties. However, higher loadings of CF to increase the conductivity of polymer composites has a detrimental effect on the mechanical and tribological performance of the material such as reduction of strength and flexibility. Improving the electrical conductivity with incorporation of fullerene (C60), while attaining higher mechanical characteristics was the prime objective of this study. 2. Experimental 2.1. Materials ABS terpolymer was purchased from Lanxess (Cologne, Germany), with the trade name Lustran® ABS M203FC. Chopped CF sample was purchased from Dowaksa (Yalova, Turkey) with the trade name Aksaca AC 0101. Fullerene (C60), with mesh size of 180–200 µm, was supplied from Acros Organics (Fisher Scientific, USA). 2.2. Fabrication of Composites The preparation steps of composites were carried out using lab-scale twin screw co-rotating micro-extruder (15 mL micro-compounder®, DSM Xplore) and injection-molding process. ABS copolymer was compounded with the loading ratios of 20 wt.% CF and 0.1, 0.5 and 1.0 wt.% of C60. 2.3. Characterization Techniques Mechanical, electrical, damping, thermal, melt-flow and structural investigations of ABS-based composites were conducted by performing tensile, impact and Shore hardness tests, conductive atomic force microscopy (AFM), dynamic mechanical analysis (DMA), thermal gravimetric analysis (TGA), melt flow rate test (MFR), scanning electron microscopy (SEM), respectively. 3. Results Nano-dimensional carbon additive donated a multi-functional character, while increasing both tensile strength and strain values for ABS/CF composite system. Thermo-mechanical investigation of composites which conducted by DMA analysis revealed that storage modulus and glass transition temperature of unfilled ABS and ABS/CF composites displayed increasing trend after C60 additions. Formation of synergy between C60 nanoparticles and CF was confirmed by electrical conduction results by achieving a conductive path with incorporation of C60 nano-particles.
