▎ 摘　　要

In this work, an insulated poly-2-amiothiazole was successfully prepared to noncovalently modify the graphene (P-AT@rGO) via an in-situ polymerization. The superior anticorrosive performance of epoxy composite coatings was well demonstrated. Results exhibit that the epoxy composite coatings with 2.5 wt.% P-AT@rGO still maintain 2. 81 x 10(8) Omega cm(2) of the polarization resistance after 30-days immersed in a 5.0 wt.% NaCl solution. Significantly enhanced protective performance of the epoxy composited coatings is attributable to the low electrical conductivity and the good dispersion of P-AT@rGO, the richer crosslinking densities, and the improved hydrophobicity.
