The adsorption and polymerization of triazinedithiols（TDTs） compounds on metal surfaces have attraced researcher′s attention due to their anticorrosion property,adhesion property,lubrication property,dielectric property and superhydrophobic property on a variety of metal substrates.The monomer layer of TDTs on metal surfaces can be polymerized photochemically,thermochemically,electrochemically or evaporatingly.The electropolymerization process offers the advantage of simultaneous formation and deposition of the polymer coatings on metal substrate from monomer-electrolyte solution.These preparation methods and application area of triazinedithiol polymeric nano-films were reviewed in this paper.The polymerization mechanisms of triazinedithiol compounds on metal surface were analyzed and discussed in detail.It is proposed that the more functional polymeric nano-film can be obtained by means of the modification of triazinedithiols（TDTs） compounds.The new application of these polymeric nano-films was prospected.
