Structure-Properties relationships in renewable composites based on polylactide filled with Tannin and Kraft Lignin - Crystallization and molecular mobility

Calorimetry and dielectric spectroscopy supplemented by polarized light microscopy, X-ray, infrared spectroscopy and scanning electron microscopy are employed here to assess the crystallization, interactions and molecular mobility in polylactide (PLA) filled with Tannin and kraft-Lignin prepared by melt extrusion. The direct and indirect effects of the fillers are investigated within two states of the polymer, namely, amorphous and...
