Abstract:
This paper reports on specific open and interconnected CO(2) foams of poly(L-lactic acid). The effect of varying gas concentration and hence physical changes induced by CO(2) has been investigated and thus used to generate specific structures. The developed morphologies have a skin core structure with larger pores in the core and open and interconnected smaller pores in the skin.
