摘 要：The objective of this study was to improve the toughness of bio-based brittle poly(ethylene 2,5-furandicarboxylate)(PEF) by melt blending with bio-based polyamide11(PA11) in the presence of a reactive multifunctional epoxy compatibilizer(Joncryl ADR?-4368).The morphological,thermal,rheological,and mechanical properties of PEF/PA1 1 blends were *** with neat PEF,the toughness of PEF/PA11 blend was not improved in the absence of the reactive compatibilizer due to the poor compatibility between the two *** Joncryl was incorporated into PEF/PA1 1 blends,the interfacial tension between PEF and PA1 1 was obviously reduced,reflecting in the fine average particle size and narrow distribution of PA11 dispersed phase as observed by scanning electron microscopy(SEM).The complex viscosities of PEF/PA11 blends with Joncryl were much higher than that of PEF/PA11 blend,which could be ascribed to the formation of graft copolymers through the epoxy groups of Joncryl reacting with the end groups of PEF and PA11 molecular ***,the compatibility and interfacial adhesion between PEF and PA11 were greatly improved in the presence of *** compatibilized PEF/PA11 blend with 1.5 phr Joncryl exhibited significantly improved elongation at break and unnotch impact strength with values of 90.1% and 30.3 kJ/m2,respectively,compared with those of 3.6% and 3.8 kJ/m2for neat PEF,*** work provides an effective approach to improve the toughness of PEF which may expand its widespread application in packaging.
