Mechanical and morphological properties of sterate modified layered double hydroxide blend with polyhydroxybutyrate/poly(lactic acid) nanocomposites

In this study, poly(3-hydroxybutyrate) (PHB)/poly(lactic acid) (PLA)/stearate modified magnesium aluminum layered double hydroxides (SMALDH) nanocomposites were prepared from PHB/PLA blend and SMALDH by solvent-casting method. The ratio of PHB/PLA was fixed at 90/10 as it gave the optimum tensile pr...
