Abstract: A preparation method of a SiC porous ceramic material and porous ceramic material manufactured by using the method, comprising: mixing a SiC aggregate, a sintering aid (zirconium oxide), a pore-forming agent (activated carbon) and a polymer binder with a reinforcing agent (SiC whiskers) according to a certain proportion, and obtaining a porous ceramic material via forming, drying and high-temperature sintering. The porous ceramic material has a high strength, a high porosity, a good thermal shock resistance and a low sintering temperature, and can server as a filter material of high-temperature flue gas and a carrier material in vehicle exhaust purification.

Abstract: The present invention relates to a method for preparing nanoporous polysulfone-based polymers, including: a copolymer of a polysulfone polymer and a polar polymer is immersed into a compound swelling agent, and maintained for at least 1 minute above room temperature; the compound swelling agent is a “solvent pair” composed of the mixture of solvent A and solvent B; the solvent A has high affinity with the polysulfone polymer; and the solvent B has high affinity with the polar polymer; the treated copolymer is taken out from the compound swelling agent and then dried to remove the solvent to obtain the nanoporous polysulfone-based polymers.
