A method for peeling laminated nano-particle, comprising the following steps: (1) intercalating laminated nano-particles with an intercalating agent to obtain intercalated nano-particles; (2) peeling the intercalated nanoparticles prepared in step (1) with a maleic anhydride graft to obtain peeled nano-particles. The present peeling method employs an intercalating agent to intercalate laminated nano-particles, so as to obtain intercalated nano-particles; and then a maleic anhydride graft is used to peel the intercalated nano-particles. Since the maleic anhydride graft contains both a polar aldehyde group and a non-polar olefin segment provided by the maleic anhydride, under high temperature and screw shearing, the anhydride and the polar group (e.g., an amine group) undergo a general dehydration reaction to form a chemical bond, thereby chemically coupling the incompatible polar and non-polar substances, achieving peeling and dispersing of the laminated nano-particles, as well as functions for coupling to improve compatibility.
