Abstract :

Polyamide 6 (PA6) is an engineering thermoplastic with the advantages of high resistance to chemicals and abrasion, high fatigue resistance and toughness. However, it has some disadvantages such as low impact strength and notch sensitivity. These disadvantages of PA6 can be improved by blending it with elastomers. Recently, thermoplastic elastomers (TPE) have been frequently used to toughen notch-sensitive polymers such as PA6 due to their superior properties such as high elasticity, recyclability and easy processing. As it is known, obtaining superior properties in polymer blends depends on the interfacial interaction between the components of the polymer blend. Additionally, by using compatibilizers, blends with the required properties can be created by enhancing interaction between phases, or interfacial adhesion. Recently, polyhedral oligomeric silsesquioxane (POSS) nanoparticles, organic/inorganic hybrid nanoparticles, are preferred as an alternative compatibilizer to conventional types. In this study, PA6/TPE blends having continuous phase TPE were compatibilized with MoEpPOSS nanoparticles with single epoxy groups for the first time in the literature. The blends were prepared using a laboratory-scale Xplore micro-compounder and then molded using a Xplore micro-injection device to obtain standard test samples. The rheological and morphological properties of PA6/TPE blends compatibilized with MoEpPOSS nanoparticle were investigated.
