ABSTRACT:
A blend of high-molecular and a low-molecular organic material contains the high-molecular organic material in a proportion smaller than that of the low-molecular organic material, and has a three-dimensionally continuous network skeleton structure formed by the high-molecular organic material. The structure preferably has an average cell or mesh diameter not exceeding 500 microns. The removal of the low-molecular organic material from the blend gives a functional porous material consisting of the high-molecular organic material. The replacement of the low-molecular organic material in the blend with a solid or liquid, or a mixture thereof, gives a functional composite material containing the solid or liquid, or their mixture in the network skeleton structure.
