چکیده:

The morphology of a ternary polymer system is a function of processing parameters, in particular, temperature. In fact, altering the operational temperature would have directimpacts on the interfacial tension between each binary domains owing to entropic contribution through the Gibbs free energy of ternary system.Consequently, the knowledge concerning with temperature effects could possibly result in morphology prediction toward polymer blends.In another word, the relation between processing temperature and morphology development is of vital importance. The currentpaper deals with the morphology prediction through the HDPE/PA-6/EVOH ternary polymer blends as a result of temperature being changed. Accordingly, the effect of temperatureon the distribusion of both dispersed phases were considered as the thermodynamic parameter. Here, based on interfacial energy contribution, by increasing the temperature within the HDPE matrix, there was an increase in the interfacial tension of composite droplets, as calculated based upon theoretical predications
