The PG is employed as nanoscale reinforcement fillers in waterborne acrylic modified alkyd resin (AMAR) coatings. The stability and corrosion resistance of the waterborne PG/AMAR nanocomposite coatings are investigated. SEM and stability of nanocomposite indicated that the PG sheet is uniformly distributed in AMAR nano‐emulsion. Potentiodynamic polarization and electrochemical impedance spectroscopy studies indicated that the PG/AMAR composite coatings exhibit higher corrosion resistance in simulated body fluid (SBF) compared with pure AMAR coatings and GO/AMAR coatings. In addition, the stability and corrosion resistance of the composite materials reach optimum when the PG content is 1%. PPS functionalized graphene (PG) displays prospective application in anticorrosion field. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.
