Functionalizing graphene with titanate coupling agents as reinforcement for one-component waterborne poly(urethane-acrylate) anticorrosion coatings

•The dispersion of reduced graphene oxide (RGO) in polymer matrix was improved.•In situ incorporation of titanate functionalized RGO into polymer was used.•Isopropyl tri(diotylpyrophosphate) titanate (T3) was a good modifier for RGO.•The compatibility and interaction between T3-RGO and polymer were improved.•The one-component coating displayed excellent long-term corrosion resistance.
