Thermally induced phase separation (TIPS) for the fabrication of porous foams based on various biodegradable polymers of poly(L-lactic acid) and its copolymers with D-lactic acid and/or glycolic acid is presented. Diverse foam morphologies were obtained by systematically changing several parameters involved in the TIPS process, such as polymer type and concentration, coarsening conditions, solvent/nonsolvent composition, and the presence of an additive. The produced foams had microcellular… CONTINUE READING
