“…Thus, it can be assumed that the morphology differences in PTT-PTMO/SWCNTs+GNPs nanocomposites do not appear to make a noticeable difference in the thermal stability of the nanocomposites. The possible explanation for such behaviour is that both the SWCNTs and graphene nanoplatelets have high electron affinities and as such seem to be capturing free radicals [30,31]. Discussed TGA results suggest that by incorporating either SWCNTs or graphene nanoplatelets or the mixture of both into the polymer, its thermo-oxidative stability should be improved.…”

Abstract. Graphene nanoplatelets/single walled carbon nanotubes/poly(trimethylene terephthalate-block-poly(tetramethylene oxide) segmented copolymer (GNP/SWCNT/PTT-PTMO) hybrid nanocomposites were synthesized via in situ polymerization. A remarkable synergistic effect between GNPs and SWCNTs on improving thermal and mechanical properties of nanocomposites based on segmented block copolymers was observed. Heterogeneous structure of the PTT-PTMO allowed for a better and more uniform distribution of both types of nanoparticles and stabilized the structure in question. This enabled us to observe a so-called 'synergistic effect', caused by the use of mixture of carbon nanotubes and graphene nanopletelets, on the enhancement of thermal and mechanical properties of the obtained polymer. In order to ascertain the influence of mentioned carbon nanostructures on the nano-phase-separated structure of the synthesized PTT-PTMO block copolymers, differential scanning calorimetric (DSC) and dynamic mechanical thermoanalysis (DMTA) measurements were performed. Scanning electron microscopic (SEM) and transmission electron microscopic (TEM) images of the PTT-PTMO nanocomposites displayed that hybrid nanofillers exhibited better distribution and compatibility than SWCNTs and GNPs did individually. The tensile modulus of 0.5SWCNT/0.1GNP/PTT-PTMO composites was 68% higher than that of the PTT-PTMO alone, compared to only a 10 and 28% increase in tensile modulus for 0.3GNP/PTT-PTMO and 0.3SWCNT/PTT-PTMO composites respectively (the highest concentration when single nanofiller was added).

“…The char yield increased from 9.1 to 15.4% due to the effects of additives. It is well known that char yield generated on a surface can act as a heat barrier and thermal insulation [44]. So it is expected that increased char yield sustained the epoxy polymer degradation.…”
