▎ 摘　　要

NOVELTY - Peelable decontamination coating comprises a combination of an aqueous polymer solution and a modified adsorption nanomaterial, where the modified adsorption nanomaterial includes a combination of a porous nanomaterial, a non-porous nanomaterial, and a complexing agent. USE - The peelable decontamination coating is used in cleaning the surface of a material (claimed). ADVANTAGE - The peelable decontamination coating has excellent decontamination efficiency and processability, is easy to peel after film coating, has excellent tensile strength, is convenient to operate, is safe and environmentally-friendly, is simple in post-treatment, and removes radioactive nuclear element pollution, heavy metal pollution, organic pollution and surface pollution in other industries and civil use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the peelable decontamination coating, comprising reacting the aqueous polymer solution with modified nano-adsorption particles to obtain the peelable decontamination coating, where the temperature of the reaction is 70-95 degrees C, and the reaction time is 10-240 minutes, and the step of adding the additive agent is further included after the reaction is completed.
