Abstract

This study produces and characterizes immiscible blend systems made with high-density polyethylene (HDPE) and post-industrial polyamide 11 (PA11) obtained from offshore. Blends were prepared at an 80/20 (wt.%) HDPE/PA11 ratio. To enhance phase compatibility, high-density polyethylene grafted with maleic anhydride (HDPE-g-MA) was employed as a conventional compatibilizer at 1.5 wt.% content. In addition, the effect of silicon dioxide nanoparticles (nSiO2) incorporated at 2 and 4 wt.% contents was evaluated. The compositions were analyzed in the presence and absence of the compatibilizer. Mechanical, thermal, rheological, and morphological analyses showed that HDPE-g-MA led to a slight improvement in the interfacial interaction between the immiscible polymer phases. Moreover, the addition of nSiO2, in the presence of the traditional compatibilizer, led to the most favorable balance of thermal and mechanical performance, suggesting that nSiO2 nanoparticles may act as effective co-compatibilizers in HDPE/HDPE-g-MA/PA11 systems.
