Magnetic nanoparticles have good superparamagnetism and magnetic target in addition to high specific surface area and hydrophilicity,which makes separation membrane magnetic.Thus magnetic nanoparticles have great application potential in the preparation and modification of separation membrane.Therefore,the applications of magnetic nanoparticles in the preparation and modification of membrane such as gas separation membrane,ultrafiltration membrane and nanofiltration membrane were summarized.The addition of magnetic nanoparticles can regulate the membrane microstructure,and improved the membrane's hydrophilicity,separation performance and anti-fouling ability.The main research direction in the future was to synthesize magnetic nanoparticles with high stability,easy dispersion and surface functionalization,so as to further controlled the microstructure and separation performance of the membrane by making full use of their magnetic properties,and the application range of the membranes could be expanded.
