    Abstract: The invention relates to processes for preparing a synthetic foam having present therein particles with a controlled particle distribution and the use of said foam, as well as to foams as such. Accordingly the invention is directed to a process for preparing a synthetic foam having present therein particles, wherein the distribution of said particles is controlled by the following steps of dissolving at least one synthetic polymer in one or more solvents to form a solution; contacting particles with said solution to form a polymer/particles mixture; and freeze-drying the polymer/particles mixture by: freezing the polymer/particles mixture; and subsequently subliming the one or more solvents to form a synthetic foam comprising said particles.

    Abstract: A method for preparing a highly porous, high surface area non-degradable material, comprises the steps of mixing a non-degradable polymer with a solvent or mixture of solvents; gelling the mixture; and treating the gel under conditions whereby a substantially solvent free porous structure is created having a porosity greater than about 80%. The resultant material is mechanically strong and has an architecture comprising at least one of nano fibrous, micro fibrous, non fibrous, complex porous structure with nano fibrous architecture, and mixtures thereof. A method for preparing a highly porous, high surface area degradable or partially degradable material, comprises the steps of mixing a degradable or partially degradable polymer with a mixed solvent comprising a first solvent and a second solvent, wherein the mixed solvent comprises a ratio higher than 1:1, first solvent to second solvent; gelling the mixture; and treating the gel under conditions whereby a substantially solvent free porous structure is created having a porosity greater than about 80%; wherein the material is mechanically strong and has a complex porous structure with nano fibrous architecture.
