【 摘 要 】

Poly(trimethylene 2,5-furanoate) (PTF) nanocomposites reinforced with few layer graphene (FLG) were preparedthrough in situ polymerization. The method in question allows obtaining well-dispersed nanoplatelets in the whole volumeof PTF matrix. The mechanical properties of the PTF/FLG nanocomposites slightly increased with as quantity of FLG assmall as 0.1 wt%, which was best seen in the improvement of elongation at break by about two times. The presence of FLGdid not affect the crystallization and chain mobility of PTF matrix. However, the incorporation of a small quantity of FLGslightly improved the thermal stability of the nanocomposites. Additionally, the cold and hot water absorption and oxygenpermittivity measurements confirmed that FLG affected the tortuosity of the diffusive path for the penetrant molecule. Moreover,along with a successive addition of FLG a linear increase in thermal conductivity was visible.
