The silver-based antibacterial composites have to release the Ag+ to a pathogenic environment in order to be effective. For improving the anticorrosive and antibacterial properties of organically modified silicate, the sol-gel method is used to obtain Ag doped siloxane solution by adding Ag into siloxane coupling agent, and then antibacterial and anticorrosive film is prepared on the aluminum alloy surface by spin coating. The effect of siloxane coupling agent and silver content on the antibacterial and anticorrosive efficacy of composite is investigated. The characterization of the composites is discussed on the basis of the structural characterization, including SEM, TEM and NMR. Additionally, electrochemical analysis and accelerated corrosion testing will be used to investigate the corrosion resistance of the composites. Taking Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus and Bacillus subtilis as target bacteria, suspension quantitative bactericidal test and inhibitory test are carried out.
