Abstract: A method for making a composite and/or structured material includes: forming a lattice construction from a plurality of solid particles, the construction being formed so as to have one or more gaps between the particles; invading the lattice construction with a fluid material such that the fluid material at least partially penetrates the gaps; and, solidifying the material which invaded the lattice construction to form a composite material. In one suitable embodiment, the method further includes removing at least a portion of the lattice construction from the composite material thereby forming at the location of the removed portion one or more pores in the solidified material that invaded the construction.

Abstract: A method for making a polymer with a porous layer from a solid piece of polymer is disclosed. In various embodiments, the method includes heating a surface of a solid piece of polymer to a processing temperature and holding the processing temperature while displacing a porogen layer through the surface of the polymer to create a matrix layer of the solid polymer body comprising the polymer and the porogen layer. In at least one embodiment, the method also includes removing at least a portion of the layer of porogen from the matrix layer to create a porous layer of the solid piece of polymer.

Abstract: A method of forming a porous article comprises forming a packed region of a soluble particulate material with a plurality of voids. A flowable polymeric material contacts at least a portion of the packed region so that it becomes disposed in at least a portion of the voids. The polymeric material is at least partially solidified to form an intermediate composite material. At least a portion of the soluble particulate material is removed from the intermediate composite to form a porous article.
