Potential Role of Nanofillers as Compatibilizers in Immiscible PLA/LDPE Blends
This article describes the use of commercial silica (SiO2) and calcium carbonate (CaCO3) nanofillers as compatibilizers in immiscible polylactide/low-density polyethylene (PLA/LDPE) blends. The general aim of the study was to investigate the possibilities of replacing standard commodity plastics such as LDPE based on non-renewable mineral oil resources with the biodegradable renewable polymer PLA in compatibilized PLA/LDPE blends for use in the packaging industry. The calculations of the minimal interfacial energy and optimal wetting abilities indicated that SiO2 filler was a better potential compatibilizer than CaCO3 for a given PLA/LDPE blend. This was due to its preferential localization at the interface. The significantly improved morphology of the ternary PLA/LDPE/SiO2 blend was found to present an increased strength, toughness, and crystallinity.
