Poly(lactic acid) (PLA)/halloysite nanotube (HNT) nanocomposites were prepared using melt compounding followed by compression molding. Maleic anhydride grafted styrene–ethylene/butylene–styrene copolymer (SEBS-g-MA) and N,N′-ethylenebis(stearamide) (EBS) were used to improve the impact properties of PLA nanocomposites. The properties of PLA/HNT nanocomposites were characterized by tensile and impact tests, Fourier transform infrared spectroscopy, thermal analysis (DSC and TGA), and morphological analysis (FESEM and TEM). In addition, the oxidation onset temperature (OOT) was determined using DSC. The PLA/HNT6/EBS5 nanocomposites gives higher impact strength improvement (98%) compared to that of PLA/HNT6/SEBS-g-MA5 (77%). Also, the PLA/HNT6/EBS5 exhibited higher OOT compared to that of PLA/HNT6/SEBS-g-MA5 nanocomposites.
