The silver nanocrystals encapsulated in mesoporous silica nanoparticles (Ag-MSN) with increased stability and enhanced antibacterial potency were prepared. The morphology of the nanoparticles was characterised by scanning electron microscopy and transmission electron microscopy. X-ray diffraction analyses proved that the silver nanocrystals were truly embedded in the mesoporous silica nanoparticles. Electrochemical impedance spectroscopy was carried out to evaluate the effects of organosiloxane films containing Ag-MSN on reducing microbial influenced corrosion. The corrosion resistance property showed that the films containing Ag-MSN could significantly decrease the Vibrio natriegens adhesion and protect the aluminium against biocorrosion in sea water.
