In previous work, the corrosion performance and anti-corrosion mechanism of galvanized steel wire embedded in vegetation-growing concrete under marine environment was highlighted. In this work, a graphene-modified epoxy coating was developed and applied to the protection of galvanized steel in vegetation-growing concrete under a marine environment. The effect of dispersed graphene on the anticorrosion performance of the epoxy coatings was evaluated. The composite coatings displayed outstanding barrier properties against H₂O molecules compared to the pure epoxy coating. Salt spray test results revealed superior corrosion resistance offered by the prepared graphene-modified epoxy coating on galvanized steel.

植物生长混凝土中镀锌钢的腐蚀和保护（II）：涂层保护

在以往的工作中，重点研究了海洋环境下植被混凝土中嵌入镀锌钢丝的腐蚀性能和防腐机理。在这项工作中，开发了一种石墨烯改性环氧树脂涂层，并将其应用于海洋环境下植被生长混凝土中镀锌钢的保护。评估了分散石墨烯对环氧涂层防腐性能的影响。与纯环氧涂层相比，复合涂层显示出对 H ₂ O 分子的出色阻隔性能。盐雾试验结果表明，在镀锌钢上制备的石墨烯改性环氧涂层具有优异的耐腐蚀性。
