The vapor grow carbon fiber impregnated in the porous material of the present invention does not contain aggregates and a three-dimensional network is formed between the fiber filaments, wherein length of each of the fiber filaments is maintained. Therefore, the vapor grown carbon fiber enables to readily produce a composite material (porous material), in which even a small amount of addition of vapor grown carbon fiber can exhibit sufficient effect.

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.
