Abstract To develop a water-borne epoxy (WEP) nanocomposite coating containing graphene oxide (GO) nanomaterials with excellent anti-corrosion property, natural and nontoxic phytic acid (PA) molecules were used to functionalize GO for improving the compatibility between GO and WEP coating. The results of Fourier transform infrared spectroscopy, Raman spectroscopy, X-ray diffraction, ultraviolet–visible spectroscopy, X-ray photoelectron spectroscopy, and atomic force microscopy indicated successful decoration of PA molecules onto the surface of GO nanomaterials. Scanning electron microscopy analysis revealed that the dispersion performance of GO in WEP was significantly enhanced owing to PA modification. The results obtained from long-term electrochemical measurements and salt spray test confirmed that addition of well-dispersed PA-GO nanomaterials could remarkably enhance the barrier and corrosion protection capability of the WEP coatings.

植酸对氧化石墨烯的绿色改性及其在防腐水性环氧涂料中的应用

摘要 为了开发具有优异防腐性能的含有氧化石墨烯 (GO) 纳米材料的水性环氧 (WEP) 纳米复合涂层，采用天然无毒的植酸 (PA) 分子对 GO 进行功能化，以提高 GO 与 WEP 涂层之间的相容性。 . 傅里叶变换红外光谱、拉曼光谱、X 射线衍射、紫外-可见光谱、X 射线光电子能谱和原子力显微镜的结果表明 PA 分子成功修饰到 GO 纳米材料的表面。扫描电子显微镜分析表明，由于 PA 改性，GO 在 WEP 中的分散性能显着增强。
