Research Progress in Organosilane Modification of Clay Minerals

(School of Applied Chemistry and Biological Technology,Shenzhen Polytechnic,Shenzhen518055,China) Abstract:Clay minerals have attracted considerable attention in basic research and practical appli-

cations due to their unique layered nanostructure.However,the hydrophilic surface of clay minerals

makes it difficult to improve the properties and limits the application of materials.Therefore,the sur-

face modification with organosilane is one of the effective methods to improve the surface properties of

clay minerals.The clay minerals modified by organosilane possess dimensional stability,adsorptivity

and barrier properties of clay minerals,and high reactivity of various functional groups in organosi-

lane molecules.Therefore,the modified clay minerals have wide applications in materials science,

environmental engineering and carrier materials.Accordingly,they have attracted much attention in

mineralogy and material science in recent years.This paper reviewed the research progress in or-

ganosilane modification of clay minerals with different types.The influence of clay mineral type,or-

ganiosilane species and reaction conditions on the structure of modified clay minerals was discussed,

and the main research directions of organosilane modification of clay minerals were prospected.

Key words:clay minerals;montmorillonite;kaolinite;organosilane;modification
