Abstract: Polymer modified montmorillonite(MMT)has better thermal stability and more structural components than alkyl ammonium modified montmorillonite,which can confer more surface properties and mechanical properties.In this paper,the latest research progress in this field was reviewed.The situation and effect of polymeric quaternary ammonium salt,copolymer quaternary ammonium salt and quaternary ammonium salt as interlayer polymerization modifier were introduced in detail.The composition,structure and properties of the organic modifier and the properties and applications of the modified nanocomposites were mainly introduced,and the future research trends were also discussed.
