Abstract: Metal wire mesh porous materials are kinds of porous materials with the controllable pores, high specific surface area, high strength, and low cost, which have been widely used in the filtration separation fields of high temperature flue gas and slurry oil, because of the high permeability and high filtration precision. Furthermore, due to the high specific surface area, open pore structure, high porosity, high strength, and adjustable graded pore size, the metal wire mesh porous materials have been paid attention in the fields of photocatalysis, combustion engine emission abatement systems, efficient heat transfer, and explosion suppression. The structure and preparation methods of metal wire mesh porous materials were briefly introduced in this paper, the application progress on the fields of filtration separation, catalysis, efficient heat transfer, and explosion suppression was emphatically summarized, and the application prospect and development direction were also proposed.
