Performance characteristics of polylactide-talc composites

Abstract

The influence of the filler – talc, its content, additional heat treatment and temperature on the physical-mechanical and thermophysical properties of polylactide materials, in particular on the surface hardness, heat resistance according to Vick and thermomechanical characteristics has been studied. The influence of filler and temperature on the resistance of polylactide materials to the action of the aqueous medium is revealed. The diffusion coefficient of water in polylactide materials and the activation energy of the diffusion process were determined. It was found that the process of water absorption by filled and heat- treated materials based on polylactide is slower and requires more activation energy of the process.
