abstract = {Poly(trimethylene terephthalate-block-tetramethylene oxide)
(PTT-PTMO) copolymer/graphene oxide nanocomposites were
prepared by in situ polymerization. From the SEM and TEM
images of PTT-PTMO/GO nanocomposite, it can be seen that GO
sheets are clearly well-dispersed in the PTT-PTMO matrix.
TEM images also showed that graphene was well exfoliated
into individual sheets, suggesting that in situ
polymerization is a highly efficient method for preparing
nanocomposites. The influence of GO on the two-phase
structure, melt viscosity and mechanical properties of
PTT-PTMO block copolymer was examined by using DSC, ARES
rheometer and tensile tests. The DSC results imply that the
introduction of GO did not affect the glass transition
temperature of PTMO-rich soft phase, melting temperature of
PTT hard phase and degree of crystallinity of the
nanocomposites. As the graphene oxide loading in the
nanocomposites increase, the enhanced Young’s modulus and
yield stress was observed. The tensile strength slightly
increased with the increase of GO from 0 to 0.5 $wt\%$ when
elongation at break was higher or comparable to the value of
neat PTT-PTMO copolymer.},
