Herein, a simple melt-blending method is utilized to disperse of halloysite nanotubes (HNTs) in polystyrene/polyolefin elastomer (PS/POE) blends. Based on morphological studies, the PS/POE/HNT nanocomposite containing up 3 phr HNTs shows excellent nanofiller dispersion, while those filled with 5 exhibit aggregation. To overcome aggregation issue, polypropylene-grafted-maleic anhydride (PP-g-MA)...
