Abstract

The invention provides a magnetic composite material. The material comprises a base material, a photocatalyst and a functional agent. The magnetic composite material has the advantages that the adopted magnetic nanometer composite photocatalyst has the high capacity for photocatalytic degradation of organic pollutants, recycling can be performed through magnets, and no stripping phenomenon is generated in the manufacturing process; due to the fact that a sodium diffusion inhibitor and a reflectivity conditioning agent are added, the quality-keeping durability of a membrane is enhanced, the tight connection degree of the components is greatly enhanced by using an adhesive and a reinforcing agent, and membrane stripping is better avoided.
