Abstract: A composite porous structure capable of absorbing organic pollutants from water is produced by preparing a dispersion of non film-forming PVC particles in a water-soluble organic liquid, impregnating a macroporous matrix such as a cellulosic sponge or paper with the dispersion, and curing the impregnated matrix by heating to achieve sintering of the PVC particles to produce a microporous substrate which is retained within the macroporous matrix.

Abstract: A method of manufacturing a separator for a polymer electrolyte fuel cell in which the specific resistance is small, and the coefficient of thermal conductivity and the gas shielding property are high and have high strength. The sintering material comprises a phenol resin coated to the surface of a powder of carbon, and the plate is a metallic plate having plating on both surfaces. After the metallic plate is arranged in a mold provided with grooves, the sintering material is filled to both sides of the metallic plate, and then they are heated and sintered. The separator for a fuel cell becomes homogeneous, and, as a result, the gas shielding property rises with high strength, because phenol resin has been uniformly distributed in the sintering material. Moreover, because oxides are not generated on the surfaces of the separator by sintering, the specific resistance will be relatively small.

Abstract: A method of manufacturing PTFE material includes preparing a mixture of PTFE resin powder and a susceptor material which is compacted and sintered by exciting the susceptor material with microwave energy. Preferably, the compaction and sintering of the mixture is carried out in a continuous process and a vacuum is drawn on the mixture in the heating zone to extract any air from the mixture. The sintered mixture may be advanced, preferably continuously, to a cutting zone where the PTFE material may be cut to any desired length preferably while the mixture is still warm to produce anywhere from thin wafer PTFE components to long tubular PTFE hose, or the like.
