چکیده
|
In this research, mesoporous silica was applied as the host of corrosion inhibitor (molybdate). the loaded mesoporous silica was dispersed in an epoxy matrix. the composite was then coated on the mild steel plate. results showed that the corrosion resistance of the scratched epoxy having mesoporous silica loaded by molybdate was better than the one without it or neat epoxy. on the other hand, edx and ftir studies showed the release of corrosion inhibitor in the scratched zone. it was due to ph-sensitive release of corrosion inhibitor in the aggressive media. also, xrd data showed the presence of mo compounds on the surface of steel.
