Biobased polymer composites for films and coatings

Abstract

Heterogeneous multicomponent biocomposites were elaborated on the basis of bio- degradable polymer polyhydroxybutyrate through incorporation of additives of distinctive chemical nature (plasticizers, renewable fillers, compatib ilizers). Plasticized polyhydroxybutyrate solutions were used as continuous matrices for the formation of films and paper coatings. Mechanical, thermal, hygroscopic, and barrier properties and biodegradation of the obtained materials were evaluated in terms of application as biodegradable packaging.
