Abstract: A process for producing a porous object is provided that makes it possible to control pore sizes, particularly not only smaller pore sizes but also larger pore sizes. The pore sizes are controlled by: preparing a mixed solution containing a polymer including a copolymer of lactide and caprolactone, a solvent in which the polymer has a relatively low solubility, and a solvent in which the polymer has a relatively high solubility and that is compatible with the solvent in which the polymer has a relatively low solubility; varying the content of the solvent in which the polymer has a relatively low solubility in the mixed solution, when the mixed solution is frozen and dried to produce the porous object; and cooling the mixed solution at a rate of 300°C/hr or lower in freeze-treating. Thus a porous object with a pore size of 30 to 1800 µm can be obtained.

Abstract: Film, fibre, foam and adhesive materials are produced from soluble S-sulfonated keratins. Once formed, the films, fibres, foams or adhesives are treated to modify the properties of the materials, in particular to improve the wet strength of the materials. Treatments used include removal of the S-sulfonate group by treatment with a reducing agent, treatment with an acid or treatment with a common protein crosslinking agent or treatment with a reduced form of keratin or keratin protein. The films are made by solvent casting a solution of S-sulfonated keratin proteins, the foam made by freeze-drying a solution of S-sulfonated keratin proteins and the fibres made by extruding a solution of a S-sulfonated keratin protein.
