NOVELTY - Organogel comprises 10-20% nano calcium hydroxide powder, 1-5% graphene quantum dots, 5-10% epoxy resin and 70-80% ethyl acetate. USE - Organogel for removing organic polymers on the surface of a mural with a non-destructive detection residual function. ADVANTAGE - The organogel can be completely removed by simply wiping with a cotton swab, and has excellent industrial production prospects. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing an organogel for removing organic polymers on the surface of a mural with a non-destructive detection residual function, which involves adding 10-20% nano calcium hydroxide powder, 1-5% graphene quantum dots and 5-10% epoxy resin to 70-80% ethyl acetate solution under stirring for 30-90 minutes, and then standing for 24-36 hours to obtain mural surface with non-destructive detection function; and (2) a method for detecting organic polymer removal on the surface of murals, which involves applying gel to the detection unit and irradiated by a 365-nanometer ultraviolet lamp at the place where the gel is applied.
