Poly(lactic acid) (PLA) is a biodegradable thermoplastic polyester produced from renewable sources that can be easily processed to obtain articles to be used in many applications, from commodities to electronics. The large influence of the crystalline structures and morphology on the biodegradation rate, as well as on the other material properties, led to an ever-increasing interest in the study of the crystallization behaviour of PLA. In this work, experiments on the crystallization kinetics of PLA were carried out by means of optical observations considering the nucleation and growth phenomena of the PLA crystals under quiescent conditions.

Abstract
Poly(lactic acid) (PLA) is a biodegradable thermoplastic polyester produced from renewable sources that can be easily processed to obtain articles to be used in many applications, from commodities to electronics. The large influence of the crystalline structures and morphology on the biodegradation rate, as well as on the other material properties, led to an ever-increasing interest in the study of the crystallization behaviour of PLA. In this work, experiments on the crystallization kinetics of PLA were carried out by means of optical observations considering the nucleation and growth phenomena of the PLA crystals under quiescent conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
