The polymeric nanofilm of triazinedithiolsilane fabricated by self-assembled technique on copper surface. Part 1: Design route and corrosion resistance

A novel design route for metal protection against corrosion is proposed for the first time, which lies in assembling two or more categories of protective groups to produce brand-new compounds and fabricating the corresponding resistance structure by means of various techniques. A kind of triazinedithiolsilane compound has been successfully synthesized as protector for copper by combining protective triazinedithiol and silane groups. The protective capability of the polymeric nanofilm prepared by heating the self-assembled monolayer (SAM) of the synthesized triazinedithiolsilane molecule was examined by electrochemical tests. The results show that the polymeric nanofilm significantly inhibits copper corrosion.
