Influence the effect of Aluminum Nitride on immiscible polyamide۶(PA۶)/polyolefin elastomer (POE) blend morphology and heat conductionproperties

In this work, the thermal conductivity properties of immiscible polyamide۶ (PA۶)/polyolefinelastomer (POE) blends are tuned by selectively localizing Aluminum nitride (ALN) particles thatare placed in the interphases. ۷۰/۳۰ (PA۶/POE) compositions, with different content of ALN, wereinvestigated. The selective localization of ALN in PA۶/POE blends is obtained by using the POEmaster batch during melt mixing. We observed that thermal conductivity of PA۶/POE/ALNcomposites with co-continuous structure when ALN is selectively located in the interface ofPA۶/POE is optimal .The pure composition (PA۶/POE) has a droplet matrix morphology, whileadding ۱۰% ALN to the ۷۰/۳۰ (PA۶/POE) and induce a co-continuous morphology and improve thethermal conductivity about nine times in compared to the pure PA۶/POE due to double percolationstructure formation .The results of morphology ,rheology , crystallinity ,Dynamic mechanical andthermal analysis confirm our claim.
