This paper reports on specific open and interconnected CO₂ foams of poly(L-lactic acid). The effect of varyinggas concentration and hence physical changes induced by CO₂ has been investigated and thus used to generatespecific structures. The developed morphologies have a skin core structure with larger pores in the core and openand interconnected smaller pores in the skin.
