Research progress of metal organic framework materials in anti-corrosion coating

In recent decades of research, organic coatings have been considered the most effective and economical measure for corrosion protection of metals. However, defects in organic coatings created during the curing reaction provide corrosion channels for corrosive media, which in turn accelerate the failure of metallic materials. Functional nanomaterials are considered to be the key to solving this challenge. Metal organic frameworks (MOFs) materials, as an emerging nanomaterial, show great potential as a durable and efficient nano-corrosion filler in organic anti-corrosion coatings. Therefore, this paper reviews the application of MOFs materials as solid corrosion inhibitors, small molecule corrosion inhibitor vehicles and modified graphene oxide in anti-corrosion coatings and looks forward to the prospect of research on their application in engineering practice.
