Biodegradable polymer composites based on polylactide and cellulose

摘要

Blends of polylactide with microcrystalline cellulose are obtained under high-temperature shear deformation. In order to improve plasticity and biodegradability of the system, low-molecular-mass poly(ethylene glycols) of various molecular masses are introduced into the composites. The mechanical and thermophysical properties of these composites, as well as their water and moisture absorptions, are studied. The morphology and biodegradability of the samples are investigated with the use of various physicochemical and biological methods.
