They found a drastic reduction in the t1/2 by 35-fold when talc was assed at only 1 wt%.
Under solution blending process, the shift from 107 to 123 C was observed when talc was added at
3 wt% [5].
Although there are many papers investigating the effect of talc on the crystallization behavior of PLA, but no paper has investigated the influence of talc particle size on the crystallization behavior of PLA.
