Abstract
- A comb copolymer (CC) is designed and prepared in present article, by grafting epoxy resin (E‐20) on poly(styrene‐co‐acrylate). The CC is used as a special dispersant, which leads to a stabilizable reduced graphene oxide (rGO) suspension in organic coatings. The dispersing mechanism is deduced as π‐π attraction between CC and rGO, which is supported by the analysis data of Fourier transform infrared (FTIR) spectra, Raman spectroscopy, scanning electron microscope, transmission electron microscope, and X‐ray photoelectron spectroscopy. The corrosion resistance of CG suspension is determined by electrochemical impedance spectroscopy, the results implies that the anti‐corrosion behavior performed obviously, and protective efficiency is up to 99.53% in Tafel analysis. © 2020 Wiley Periodicals, Inc.
