Investigation of the Influence of UV Radiation on Compositions of Polylactide with Graphite Nanoplatelets
Composites of polyether polylactide (PLA) synthesized from natural raw materials with graphite nanoplatelets (GNPs), which represent a new type of composite materials based on biodegradable polymers, are obtained by the solid-phase method under the action of shear deformations. The porosity of the composites is evaluated and their electrical and mechanical properties are studied. The effect of UV radiation on the molecular weight and molecular weight distribution of PLA in PLA–GNP composites of different composites is investigated using the method of exclusion chromatography, and the effect of GNP nanofiller content on the change of their mechanical characteristics in the process of radiation is shown.
