A method of preparing a porous polymer structure comprising the steps of: forming a liquid composition comprising at least one polymer dissolved in at least one solvent; subjecting the liquid composition to stress, and if necessary also to a reduction in temperature, to cause the liquid composition to form a bi-continuous phase separated composition, the bi-continuous phase separated composition comprising a polymer rich phase and a polymer poor phase; solidifying the at least one polymer in the polymer rich phase; and removing the polymer poor phase from the polymer rich phase to provide the porous polymer structure having a bi-continuous morphology from the polymer rich phase. |
