Biodegradable Composites Based on Polylactide and Starch

Аннотация

Biodegradable composites based on polylactide and starch are obtained via solid-phase mixing with shear deformation. The effects of poly(ethylene glycol) plasticizers of different molecular masses on the mechanical characteristics, water absorption, and biodegradability of the composites are studied. The crystallinity of samples is assessed using x-ray structure analysis before and after soil exposure. Their morphology is studied using scanning electron microscopy.
