Modifying the toughness of poly(lactic acid) with various plasticizers: Areview

Due to the need of industries for polymers with good mechanical properties and biodegradability toreduce waste, the use of poly(lactic acid) (PLA) is increasing despite existing limitations. The aim ofthis research is to reduce the limitations of processing and improve the use of PLA in variousapplications, such as disposable containers, food packaging, medical industries, and so on, which arehindered by the brittleness of this polymer. One of the ways to address the brittleness of poly(lacticacid) is to use plasticizers, which reduce melt crystallinity, viscosity, and glass transition temperature,increase amorphous content and processability, and improve the toughness of PLA.
