Abstract:By modifying and optimizing the procedures, which were well described and understood for the synthesis of macroporous alumina, mesoporous alumina-based film has been successfully prepared, In this paper, the orderly mesoporous Al2O3 thin film was prepared by electrochemical workstation, and via supported N-octyltriethoxysilane (NOS) coupling agent, corrosion inhibitors be loaded into the different pore sizes of mesoporous alumina films. The physicochemical properties of this thin inhibitors carrier film were characterized. Corrosion resistance of mesoporous alumina and honeycomb ceramic macroporous alumina were compared; the conclusion shows that mesoporous alumina film can be used as good corrosion inhibitors carrier and bring out a high-efficiency inhibition result. Simultaneously, by compared with corrosion inhibition of different pore sizes (20-50nm) mesoporous alumina who absorbed NOS, and a general relationship between the different mesoporous alumina pore sizes and the adsorption capacity of NOS was obtained.
