The effects of two types of carbon nanotubes, namely multiwall (MWCNT) and single-wall (SWCNT) carbon nanotube, on the thermal and mechanical properties of acrylonitrile-butadiene-styrene (ABS) nanocomposites, have been investigated. ABS filled-CNT nanocomposites with various filler loadings of 5–10 wt% were properly produced by a solvent-free process in blend compounding at 190 °C. Compression moulded plates and extruded filaments were obtained at 190 °C and 230 °C, respectively. Melt flow index (MFI), shore hardness, Vicat temperature, differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA) were performed to characterize and compared the different CNT nanocomposites. ABS/SWCNT composite filaments showed higher tensile properties (i.e., stiffness and strength), than ABS/MWCNT. The electrical resistivity of ABS/SWCNT and ABS/MWCNT filaments decreased to 0.19 Ω.cm and 0.65 Ω.cm for nanocomposites with 10 wt% of nanofillers; a power law was presented to describe the electrical resistivity of composites as a function of the CNTs content. A final comparative parameter regarding melt flow, stiffness and conductivity was also evaluated for understanding the combined effects of the nanofillers. SWCNT nanocomposites exhibited better overall cumulative results than MWCNT nanocomposites.

Multi-walled carbon nanotubes (MWCNTs)/acrylonitrile butadiene styrene (ABS) nanocomposites were prepared by melt blending and then filaments were obtained by melt extrusion method. The Scanning electron microscope (SEM) exhibited good dispersion of MWCNTs in the SAN phase of the ABS matrix. The rheological results showed that incorporation of MWCNTs into ABS resulted in higher storage modulus (G′) and loss modulus (G′′) than those of ABS, especially at low frequencies. The tensile strength and modulus of MWCNT/ABS nanocomposite filaments substantially increased with the MWCNTs content while the elongation at break decreased. Additionally, the addition of MWCNTs decreased the coefficient of linear thermal expansion. This study provides a basis for further development of MWCNT/ABS nanocomposites used for FDM process with desirable mechanical properties and good dimension stability.
