The invention discloses a peeling method of a layered material and a high-quality peeling material obtained by peeling. The method comprises the following steps: 1) mixing the layered material and anintercalating agent to achieve infiltration of the layered material by the intercalating agent; 2) adding an activating agent to allow the activating agent reacted with the intercalating agent, so that the physical impact of a generated gas flow on the layered material causes the sheet layers of the layered material to peel, thereby resulting in a dispersion solution of a peeling material precursor; and 3) mixing the obtained dispersion solution of the peeling material precursor with a dispersion medium, and performing physical disintegration on the obtained dispersion system so as to obtain adispersion solution of the peeling material.
