Abstract
A method of preparing a modification-free, recyclable and photothermally-driven self-repairing epoxy anticorrosion coating. A bisphenol A epoxy resin is employed as a film-forming material, and a polybasic acid is used as a curing agent. A carbon material is introduced as a photothermal filler to construct a catalyst-free epoxy-anhydride curing system, which is cured at 110-130° C. for 4-12 h to obtain the recyclable and photothermally-driven self-repairing epoxy anticorrosion coating.
