Abstract The purpose of this work was to study the effect of hydrothermal, biological and photo degradation on
natural fi bres reinforced biodegradable starch-based (Mater-BiKE) composites to characterize the structural
changes occurring under exposure to different environments. The composites water-uptake rate was hindered
by the interfacial interactions between matrix and fi bres. Thermal, structural and morphological analysis
provided useful information about the irreversible changes in the properties of the composites caused by
degradation in soil and photodegradation, and their synergetic effects. The effects due to the photo-oxidation
and degradation in soil on the composites depended on the different chemical composition of… More >
