As is a kind of layered silicate minerals,kaolinite could be intercalated by some organic compounds to form kaolinite organic intercalation complexes. Functional materials based on kaolinite organic intercalation composites have received widespread attention,and which is one of the research hotspots of applied mineralogy. This paper introduces the research history and current status of kaolinite organic intercalation composites and nano-kaolinites. Also,the main influencing factors,intercalation mechanism,characterization of kaolinite organic intercalation composites,and preparation of nanokaolinite based on kaolinite organic intercalation were summarized. The outlook was made in this research field.
