Description

Technical field[0001]The present invention relates to the field of membrane material, and more particularly to a biocompatible magnetic porous membrane material and a preparation method thereof.Background technique[0002]The membrane material can be divided into a separation membrane, identify film, reaction film, energy conversion film and electronic function film, etc., and the film material has been widely used in sewage treatment, bioengineering, food, environmental protection. With the research and development of membrane materials, membrane materials are applied to more and more fields, so higher requirements are proposed for membrane materials. Some of the membrane materials in certain areas require microorganisms or cells to achieve their functions. Therefore, this type of film material needs to have biocompatibility, providing the microorganism to the ability to provide nutrients, but the current film material makes the microorganism and cells attached to the above, and the ...
