Abstract: Poly(trimethylene terephthalate)-block-poly(tetramethylene oxide) (PTT-PMTO) copolymer-based nanocomposites containing a combination of single-walled carbon nanotubes (SWCNTs) and graphene nanoplatelets (GNPs) as carbon nanofillers were investigated to determine their thermal conductivities. Nanocomposites having a total carbon nanofiller concentration of 0.4 and 0.6 wt. % were preparared with varying amounts of each nanofiller, and the thermal conductivity was measured using the transient plane source (TPS) method. The dispersion of the nanofillers was observed by SEM, and it was found that the GNPs were better dispersed when SWCNTs were present. The thermal conductivity enhancement reached a maximum when the SWCNT:GNP ratio was 5:1.
