Development Progress and Tendency of Asymmetric Porous Metal

Asymmetric porous metal material is a kind of porous material with good performance.Its structure meets the requirements of high-precision,large flux of modern filter industry and the good mechanical properties makes it a wider range of applications than ceramic membrane.In this paper,the research progress on the asymmetric porous metal material is reviewed and the development trend of the asymmetric porous metal material is forecast.
