Porous materials, methods of making and uses
The present specification discloses porous materials, methods of forming such porous materials, materials and devices comprising such porous materials, and methods of making such materials and devices.
1. A method for forming a porous material, the method comprising the steps of:
a) coating porogens with a matrix material base to form a matrix material-coated porogen mixture;
b) filtering the matrix material-coated porogen mixture through a sieve to remove excess matrix material;
c) pouring the filtered mixture into a mold;
d) treating the filtered mixture to form a scaffold comprising fused porogens and cured matrix material, wherein the scaffold comprises a three-dimensional structure in the form of the mold; and
e) removing the fused porogens from the scaffold, wherein fused porogen removal results in a porous material comprising the cured matrix material defining an array of interconnected pores.
2. The method of claim 1 wherein in the scaffold comprises a three-dimensional structure wherein the diameter of substantially all the connections between each fused porogen in between about 15% to about 80% of the mean porogen diameter.
3. The method of claim 1 wherein the cured matrix material exhibits an elastic elongation of at least 80%.
4. The method of claim 1 wherein the matrix material is a silicone elastomer.
