Magadiite is a new type of layered nano-silicate material, which has the advantages of large specific surface area, high cation exchange, strong adsorption and good inter-layer swelling performance. It has become one of the most promising potential for nano-material modified polymers. This article mainly summarized the common preparation methods of magadiite/polymer nanocomposites, including polymer intercalation, monomer in-situ intercalation polymerization and anchor intercalation polymerization. The magadiite/polymer nanocomposites prepared by three methods at home and abroad based on polystyrene, polypropylene, epoxy resin, nylon 6, polycaprolactone and polymethylmethacrylate were discussed. The solution to the incompatibility of the interface and the uneven distribution of magadiite in the nanocomposite structure was proposed, and the influence of magadiite on the structure and properties of the nanocomposite was explained. Finally, the outlook for the development of magadiite/ polymer nanocomposites was presented.
