Anti-corrosion method for realizing accurate release of corrosion inhibitor through intelligent self-sensing

The invention discloses an intelligent self-sensing corrosion prevention method for realizing accurate release of a corrosion inhibitor, which comprises the following steps: 1, reacting styrene with NaOH under the action of an initiator to obtain a Ps microsphere dispersion liquid; 2, dissolving CTAB (cetyltrimethyl ammonium bromide) into an alcohol-water solution, adding the Ps microsphere dispersion liquid, saturated ammonia water and tetraethyl silicate, centrifugally washing, drying and calcining to obtain porous hollow SiO2 microsphere powder; (3) adding the hollow SiO2 and the 3-aminopropyltriethoxysilane into the absolute ethyl alcohol, so as to obtain SiO2-NH2 (silicon dioxide); 4, adding a double-selenium compound into the SiO2-NH2 particles and toluene, and carrying out centrifugation, washing and vacuum drying, so as to obtain SiO2-NH-DSe; and 5, dipping benzotriazole into the SiO2-NH-DSe, and drying, so as to obtain the functionalized hollow SiO2 microspheres loaded with the BTA.
