Accelerated weathering of poly(lactic acid) and its biocomposites: A review

Currently, poly(lactic acid) (PLA) and its natural fiber biocomposites have a growing interest as a sustainable and biodegradable alternative to conventional polymers. Their intrinsic susceptibility to weathering degradation limits their applications. This review discusses the accelerated weathering of PLA and how fillers, reinforcements, and additives affect photo-degradation. The changes in molecular weight, thermal and mechanical properties,...
