In this study, the nanocomposites based on poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P(3,4)HB) and three kinds of aluminum-containing layered double hydroxides (LDHs) were prepared via melting intercalation. The thermal stability,thermal combustion and thermomechanical properties for these systems were systematically investigated. Both x-ray diffractometry and transmission electron microsco…
