聚乳酸／PBAT合金的微孔发泡行为研究
Study on Microcellular Foam Properties of PLA/PBAT Blends
摘要
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 tμm and a cell density of 109～1011 cells/cm3.关键词
