The content of BC in PLA was changed between 5 and 20 wt%. By increasing the BC content of the composite DSC measurements showed an increase of crystallinity (χ c ). Annealing at 90?C resulted in a further increase of χ c . Analysis of the dynamic mechanical behavior showed a sharp decline of the storage module (G’) above the glass transition temperature (T g ) while such a sharp decline did not occur for annealed samples. This indicates that the stiffness of PLA even above T g can be improved by BC and annealing. 展开更多
