Abstract
ABSTRACTThe objective of this work is to enhance the toughness of In the current study, inherently brittle polylactic acid (PLA) has been toughened using a biobased polyester without compromising the biocompatibility, renewability, strength and thermal properties of PLA. For this purpose, biodegradable Renewable resources resource based flexible aliphatic polyester (BBPE) has been synthesized and the same has been confirmed by FTIR and 1H NMR. Melt blending of BBPE elastomer with PLA in presence of free radical initiator dicumyl peroxide (DCP) leads to the development of crosslinked PLA/BBPE (PBE) blends of tunable properties. Additionally, the mechanical, morphological, thermal, crosslink density and water absorption behaviour of PBE blends were explored. It was observed that the synthesized biobased BBPE elastomers contribute to toughening of the PLA matrix consequently, improving the its impact strength and elongation at break. of the blend
