Microcellular Foaming of Biodegradable PLA/PPC Composite Using Supercritical CO2

摘要：

　　Poly (lactic acid) (PLA)/poly (propylene carbonate) (PPC) composite foams were microcellular foamed with CO2 through a batch foaming process.The influences of PPC contents,foaming temperature, and saturation pressure on the cell structure and foam density were investigated.The biodegradable PLA/PPC composite foam showed a controlled structure of microcellular and nanocellular.With an increase in saturation temperature and pressure, the cell size was increasing and both the cell density and foam density were decreased simultaneously.
