摘要

Both poly (lactic acid)(PLA) and poly (ethylene glycol)(PEG) are biodegradable polymers,and blending PLA with PEG is expected to toughen PLA matrix while maintain its biodegradability.In this study,PLA/PEG blends in different ratios were prepared through triplescrew extruder,and the foaming behavior was investigated using supercritical carbon dioxide as physical blowing agent.The mechanical,thermal,rheological properties and crystallization behavior were also studied.
