Abstract
A method is provided for fabricating a porous elastomer, the method comprising the steps of: providing a predetermined amount of a liquid elastomer and a predetermined amount of a porogen; mixing the liquid elastomer and the porogen in vacuum until a homogenous emulsion without phase separation is formed; curing the homogenous emulsion until polymerizations of the emulsion is reached, thereby forming a cured emulsion; and removing the porogen from the cured emulsion. The method can advantageously be used for forming biocompatible porous elastomers and biocompatible porous membranes.
