Abstract: Poly(lactic acid) (PLA)/poly(butyleneadipatecoterephthalate) (PBAT) blends were prepared by melt blending with the aid of chain extender (CE) and nucleating agent (PPZn). Dynamic rheological characterization and differential scanning calorimetry analysis indicated that the melt strength and crystallization of PLA were improved by addition of CE and PPZn, respectively. Microcellular foams based on PLA/PBAT blends were prepared under the optimal condition developed by this work, and the foams obtained a cell size of 1~4 μm and a cell density of 109~1011 cells/cm3.
