Abstract:   Montmorillonites（MMT）have attracted considerable attention in fundamental research and applications. Organic montmorillonites / polymer nanocomposites exhibit superior characteristics in comparison with pure polymer constituents due to its unique one-dimensional layered structure. The types of organic modifier and research advances in organic modification montmorillonite were summarized. Also unique properties of organically modified montmorillonite/polymer nanocomposites were introduced，and the developing trend of the organic modifier were predicted. In order to broaden the application of montmorillonite，different types of organic modifier were developed for polymer/montmorillonite nanocomposites in order to improve the properties，improved heat and flame resistance and so on. including mechanical strength
