Effect of talc and diatomite on compatible, morphological, and mechanical behavior of PLA/PBAT blends

open access: yese-Polymers, 2021
Biodegradable nanocomposites were prepared by melt blending biodegradable poly(lactic acid) (PLA) and poly(butylene adipate-co-butylene terephthalate) (PBAT) (70/30, w/w) with diatomite or talc (1–7%). From the SEM test, the particles were transported to
