Abstract
A method of forming a porous structure involves mixing a solvent with a curable material which disperses in the solvent such that the mixture has greater than 50% solvent content. The mixture is deposited on a substrate and viscosity of the mixture is increased. The curable material in the mixture is cured while a shape of the curable material is maintained by the solvent. After curing, the solvent is removed from the structure.
