COMPARATIVE THERMAL AND RHEOLOGICAL STUDY OF AROMATIC AND ALIPHATIC POLYAMIDE NANOCOMPOSITES AND FILMS

摘要

In this study, rheological and thermal properties of polyamide 6 (PA6), poly (m-xylene adipamide) (MXD6) and their commercial nanocomposites (4 wt. % clay) were studied. Dynamic rheological experiments were carried out for both neat resins and corresponding nanocomposites at different temperatures. Crystallinity and thermal transitions of the materials are established via both DSC and XRD techniques. Water vapor permeability (WVP) and oxygen transmission rate (OTR) of films were also measured and normalized (multiplied) by the films thickness.
