摘要：An opaque polylactide/poly(ethylene-co-vinyl alcohol) (PLA/EVOH 90/10 w/w) blend was made transparent by reactive compatibilization. In the presence of a multifunctional epoxy compound and zinc stearate, the dispersed domain size of EVOH in the blend and its distribution decreased significantly based on the morphological and dynamic light scattering analysis. Consequently, the light transmission at 700 nm increased from 9.3% for the incompatibilized sample to 83.5% for the compatibilized sample. A significant difference in the transparency of the samples can also be confirmed by naked eye. Meanwhile, the barrier property to water vapor of the compatibilized blend was maintained. The transparent PLA blend with improved water vapor barrier property has potential application in the packaging industry. (C) 2012 Elsevier B.V. All rights reserved.
