Abstract

The properties of polylactic acid (PLA) may be modified by the addition of clays or the incorporation of ionic liquids (IL). The effects of clays depend on degree of polymer intercalation and the presence of clay organomodifiers. Some ionic liquids act as plasticizers and lubricants reducing glass transition temperature (Tg) and melt viscosity, the effects depending on the IL structure and its polymer miscibility. This article compares the effects of different cationic or anionic clays and different ILs on the thermal, hydrolytic and soil degradation of PLA as measured by molecular weight (MW) changes and relates to the structure of the additives and their degree of dispersion/dissolution in the polymer melt.
