Abstract 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 × 108 Ω cm2 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.

基于绝缘聚 2-氨基噻唑非共价功能化石墨烯的优异防腐涂层

摘要 在这项工作中，通过原位聚合成功制备了绝缘聚 2-胺噻唑以非共价修饰石墨烯 (P-AT@rGO)。环氧复合涂料优越的防腐性能得到了很好的证明。结果表明，含 2.5 wt.% P-AT@rGO 的环氧复合涂层在浸入 5.0 wt.% NaCl 溶液 30 天后仍保持 2. 81 × 108 Ω cm2 的极化电阻。环氧复合涂层的保护性能显着增强，这归因于 P-AT@rGO 的低电导率和良好的分散性、更丰富的交联密度和改进的疏水性。
