Generation of Porous Microcellular 85/15 poly (DL-Lactide-co-Glycolide) Foams Using Supercritical CO2 for Biomedical Applications


 Porous 85/15 poly (DL-lactide-co-glycolide) or PLGA foams were produced by the pressure quench method using supercritical CO2 as the blowing agent. The effects of saturation pressure and temperature on average cell size and relative density of the resulting foams were studied. Porous PLGA foams were generated with relative densities ranging from 0.107 to 0.232. Foams showed evidence of interconnected cells with porosities as high as 89%. The cell size ranged from 30 to 70 microns.
