Corrosion inhibition coatings with thiirane crosslinkers and methods thereof

Abstract

A corrosion inhibitor coating composition includes a polymerized thiosemicarbazone, and a thiirane crosslinker, where the thiirane crosslinker is a difunctional molecule. The corrosion inhibitor coating composition can include where the thiirane crosslinker may include an aliphatic thiirane, a tri-functional thiirane, a bisphenol thiirane, or a combination thereof. The corrosion inhibitor coating composition can be metal-free and catalyst-free. An article utilizing and a method of preparing a corrosion inhibitor coating composition is also disclosed, which can include adding a thiourea to a difunctional epoxy terminated molecule in solution in the presence of a catalyst, converting the difunctional epoxy terminated molecule to a thiirane terminated difunctional molecule, and purifying the thiirane terminated difunctional molecule to produce a thiirane.
