针对目前接地网材料的严重腐蚀问题，研究一种高性能导电防护涂层。以氟碳树脂(FEVE)为成膜剂，采用十六烷基三甲基溴化铵(CTAB)改性石墨为导电填料，成功制备了一种新型的具有高导电性能的复合氟碳导电防腐杂化涂层材料。采用傅里叶变换红外光谱仪(FTIR)、扫描电镜(SEM)和 X 射线光电子能谱仪(XPS)表征改性前后石墨的结构以及涂层表面的微观形貌，根据国标测定涂层体积电阻率，并深入探讨涂层的导电机理。实验结果表明：CTAB 与石墨以范德华力结合，增强了石墨在氟碳树脂中的分散性能；石墨的加入，增强了氟碳涂层的导电及耐热性能，完全满足接地网防护涂层的性能要求。

Aiming at the serious corrosion of the conductive coating used in grounding grid,a con-ductive coating with outstanding performance was developed in this paper.A novel composite flu-orocarbon anti-corrosion coating material with excellent conductivity was successfully fabricated with fluorocarbon resin (FEVE)and graphite modified by Cetyltrimethyl Ammonium Bromide (CTAB)as matrix and conductive filler respectively.Fourier transform infrared spectroscopy (FTIR),Scanning electron microscope (SEM)and X-ray photoelectron spectroscopy (XPS)were employed to characterize the structure change of graph...
