摘要/Abstract

摘要： 传统的石墨烯防腐涂料存在填料成分不均一、防腐性能低、涂层不稳定等问题。为了提高石墨烯防腐涂料的分散性能和防腐性能，本文采用改进原位聚合法合成的石墨烯（rGO）/聚吡咯（PPy）复合物为填料，水性环氧树脂（EP）为成膜物质，制备新型石墨烯/聚吡咯水性防腐涂料（rGO/PPy/EP）。采用X射线衍射（XRD）、傅里叶红外光谱（FTIR）、拉曼光谱（Raman）、扫描电子显微镜（SEM）和透射电子显微镜（TEM）对涂料进行结构分析，通过塔菲尔极化曲线（Tafel）、交流阻抗谱图（EIS）和腐蚀形貌分析测试rGO/PPy/EP对Q235碳钢的防腐性能。结果表明：采用改进原位聚合法制备的rGO/PPy/EP涂料分散性好，结构致密。质量分数为1% rGO/PPy/EP涂料的腐蚀电位E_corr=-613mV，腐蚀电流密度I_corr=46.42μA/cm²，对裸钢的保护度P_i=91.02%。与rGO/EP涂料相比，rGO/PPy/EP涂料的腐蚀电流密度降低了38.62µ；A/cm²，对O₂和H₂O腐蚀介质具有较高的屏蔽性能。因此，原位聚合法制备的rGO/PPy水性涂料具有环境友好、分散性能强、结构稳定和防腐性能优异等优点，具有广阔的应用前景。

Abstract: Inherent shortcomings of the traditional grapheme anticorrosive coatings include inhomogeneous packing components,low anticorrosion performance,and unstable paintcoat. To improve the anticorrosion performance and dispersibility of the graphene anticorrosive coating,an innovative grapheme(rGO)/polypyrrole(PPy)/waterborne epoxy resin(EP)was prepared using rGO/PPy and EP as fillers and film forming material,respectively. The modified in situ polymerization method was applied to prepare rGO/PPy complex. The structure of the coating composition was characterized by X-ray diffractometer(XRD),fourier infrared spectrum(FTIR),raman spectra (Raman),scanning electron microscope(SEM)and transmission electron microscopy(TEM),respectively. The anticorrosive performance of rGO/PPy/EP coating on Q235 carbon steel was determined by Tafel polarization curves(Tafel),impedance spectra(EIS)and corrosion morphology. The results showed that the rGO/PPy coating prepared by modified in situ polymerization method had excellent dispersibility and compact structure. The corrosion potential E_corr,the corrosion current density I_corr and the protection of bare steel P_i of the 1% rGO/PPy/EP coating were -613mV,46.42μA/cm² and 91.02%,respectively. Compared with rGO/EP anti-corrosive coating,the corrosion current density of rGO/PPy/EP coating was decreased by 38.62μA/cm². Furthermore,the rGO/PPy/EP coating possessed excellent barrier properties to O₂ and H₂O. In conclusion,the rGO/PPy/EP anticorrosive coating prepared by in situ polymerization method was promising as it was environment-friendly,excellent in dispersibility,stable in structure and outstanding in anticorrosion.
