Thermal and mechanical analysis of ABS and G-ABS composites.
a, Representative DSC curves of ABS and G-ABS composites. The Tg value slightly increased as the graphene loading in composites increased, calculated from the DSC curves. b, Loss factor (tan δ) derived from DMA. In all prepared samples, pure ABS claims the highest tan δ. by adding graphene sheets into ABS, ABS’s chain mobility was constrained with graphene’s stiff frameworks, which induces smaller tan δ values. c,d, TGA and TMA curves of ABS and G-ABS composites as a function of temperature. CTE values were calculated from the linear region (RT to 110 °C) in TMA.
