“…To the best of our knowledge, there is relatively few reports regarding the ternary blends incorporating nano‐materials, and also there is no comprehensive study on the PA‐6/ethylene vinyl alcohol (EVOH)/SEBS/nanoclay nanocomposites. Our previous researches demonstrated that there are some fascinating prospects of research in the field of this class of materials, which deep understanding and controlling the affecting parameters can help us to achieve desired properties . Therefore, this research tries to uncover the structure‐property relationships in these class of nanocomposites.…”

In this way, the effects of nanoclay type, namely, Cloisite 15A and Cloisite 30B, and processing conditions on the degree of dispersion and distribution of the nanoclay, and consequently, on the morphological, rheological, and mechanical properties of the PA-6/EVOH/SEBS ternary blends would be studied.…”

This work presents the investigation of properties of polyamide‐6 (PA‐6)/ethylene vinyl alcohol (EVOH)/styrene‐ethylene‐butylene‐styrene (SEBS) ternary blends and related nanocomposites with nanoclays. In this way, the effect of the mixing protocol and nanoclay type on the morphology, mechanical, and rheological properties of the blends was comprehensively studied. Scanning electron microscopy (SEM) observation revealed that, for the neat ternary blends, core‐shell droplets were formed in which SEBS droplets were encapsulated by EVOH phase in the PA‐6 matrix. In this regard, experimental observations were compared and discussed with the predictions of phenomenological models. According to the X‐ray diffraction analysis, the distribution and degree of dispersion of the nanoclays were significantly influenced by mixing protocol. It was demonstrated that competition between the intrinsic effect of the nanoclay on the physical properties and its inhibiting effect on the interactions between PA‐6 and EVOH phases led to some interesting observations for the rheological and mechanical properties of the ternary blends. The results revealed that optimum properties could be obtained by selecting appropriate nanoclay and mixing protocol.
