In order to improve the compatibility between the poly(butylene succinate) (PBS) and multi-walled carbon nanotubes (MWNTs), Jeffamine((R)) Polyetheramines were grafted onto MWNTs. The results show that excellent dispersion of nanotubes in the PBS matrices was achieved. An improvement in thermal properties of the PBS/MWNTs nanocomposites was also observed. With the addition of 3.0 wt% MWNT-2070D, the T-d of the nanocomposite was 10.1 degrees C higher than that of the pristine PBS sample. Apart from that, the increments of E' and E" of the nanocomposite at 25 degrees C were 113 and 116%, respectively. In the aspect of conductivity, the surface resistivity decreased from 2.35 x 10(14) Omega/square for neat PBS to 5.88 x 10(3)Omega/square for the nanocomposites with a 3.0 wt% of MWNT-2070D. Such PBS/MWNT-2070D nanocomposites are potentially efficient for anti-static purposes, even electrostatic discharge and EMI shielding, which can be applied in electronic materials.
