Abstract: Researchers in this study aimed to develop polymer composites with high thermal conductivity, using polystyrene (PS) and multi-walled carbon nanotubes (MWNTs). These composites were prepared by ultrasonic radiation, through a simple-solution-evaporation method. Poly(styrene-co-maleic anhydride) (PSMA), with a benzene group and experiencing a strong affinity for PS was used as a base, to allow the MWNTs to be dispersed within the composite (MWNT-g-SMA). Results determined that the addition of MWNTs to the PS increased thermal conductivity, but mechanical properties faltered. However, with the addition of MWNT-g-SMA (33.3 vol %), the mechanical properties were improved to an extent, all the while maintaining a higher thermal conductivity (0.89 W/mK). Also, a linear trend of thermal conductivity with increasing MWNT-g-SMA content, was noted.
