Anti-corrosion reinforcement of waterborne polyurethane coating with polymerized graphene oxide by the one-pot method

The research and preparation of excellent anti-corrosion coatings is still a difficult task and critical to practical applications. In this paper, phosphoric acid, dodecylbenzenesulfonic acid (DBSA), and polyaniline (PANI) were polymerized in-situ onto graphene oxide (GO) by the one-pot method to pr...

Summary:The research and preparation of excellent anti-corrosion coatings is still a difficult task and critical to practical applications. In this paper, phosphoric acid, dodecylbenzenesulfonic acid (DBSA), and polyaniline (PANI) were polymerized in-situ onto graphene oxide (GO) by the one-pot method to prepare dodecylbenzenesulfonic acid-PANI/phosphorylated graphene oxide (DPPGO). The results of TEM, FTIR, Raman spectrum, XRD, TGA, and XPS analysis showed that the DPPGO was successfully prepared. The SEM observations showed that DPPGO has best dispersibility and compatibility than GO and PANI/phosphorylated graphene oxide (PPGO) in waterborne polyurethane (WPU) matrix. To achieve anti-corrosion performance, a new type of graphene-based polymer nanocomposites water-based coating was developed and tested by electrochemical measurements. Through a series of electrochemical tests, it is concluded that the anti-corrosion performance of a composite coating DPPGO is significantly improved. The excellent anti-corrosion properties are due to the perfect dispersion and good compatibility of DPPGO in WPU.
