Soil burial biodegradation of PLA/hydrolysed collagen/silver nanoparticles bionanocomposites

Abstract

In this study we evaluated the degradation behaviour of some polymeric bionanocomposites based on polylactic acid (PLA), hydrolysed collagen (HC) and silver nanoparticles (AgNPs) obtained by melt processing, by exposure at soil action for 30 days and 60 days. The quantification of the bionanocomposites' degradability was investigated by the weight loss determination, evaluation of the morphology-Scanning Electron Microscopy (SEM) measurements and the thermal parameters by Differential Scanning Calorimetry (DSC) measurements. From the obtained results we can observe that the polymeric composites based on hydrolysed collagen has degraded.
