Compositions for forming porous materials and three-dimensional objects, including fibers, films and coatings made from the materials are provided. Also provided are methods for forming the porous objects from the compositions. The compositions include a solvent, a polymer binder that is soluble in the solvent, and solid particles that are insoluble in the solvent. The solid particles include water-soluble salt particles that can be selectively dissolved from objects made from the compositions to render the resulting structures porous.
