Title Morphology prediction in HDPE/PA-6/EVOH ternary blends: defining the role of elasticity ratio
Date 07.08.2012
Number 34185
Abstract The morphology of uncompatibilized HDPE/PA-6/EVOH ternary blends was predicted using static and dynamic phenomenological models wherein PA-6 to EVOH component ratio and temperature were chosen as influential parameters. The type of morphology and particle size in HDPE/PA-6/EVOH blends are then examined by scanning electron microscopy and image analysis techniques. The core–shell structure was observed for all ternary samples, in which PA-6 domains were encapsulated by a thin layer of EVOH within HDPE matrix. Among various criteria, that is, viscosity ratio, interfacial tension, and elasticity ratio, the elasticity ratio has been found to be the most influential parameter for investigation of core–shell size alteration with temperature and component ratio.
