石墨烯超凡的不可渗透性能、优异的热学性质及二维结构，使其在换热设备表面防腐蚀涂层开发中具有得天独厚优势，然而，石墨烯的腐蚀促进效应却极大地限制了其防腐作用的发挥。因此，本课题拟将分子改性技术与石墨烯-高分子复合材料制备方法相结合，探索一条制备高性能导热石墨烯防腐涂层的新途径。首先，通过系统考察石墨烯电学和电化学性质对腐蚀促进效应的影响，揭示石墨烯腐蚀促进机理，前期研究结果已经初步证明了这种影响关系的存在。然后，借助分子改性技术，通过氟化改性调控石墨烯电导率和电化学活性以抑制其腐蚀促进效应，通过深入解析氟化石墨烯键结构与电化学活性及电导性之间的关联机制，从分子层面找到克服石墨烯腐蚀促进效应的措施。最后，优化涂层结构及工艺，赋予其滴状冷凝强化传热功能，制备高性能导热防腐功能涂层。本课题的实施不仅可为高性能导热防腐蚀涂层的开发提供理论依据，并且对能量回收过程中腐蚀难题的解决具有重要实际意义。

Graphene with ultrathin 2D structure, superior thermal conductivity and impermeatability displays unique advantages for applications in corrosion protection of heat transfer equipments. However, the corrosion promotion effect of graphene hinders their practical applications in corrosion protection. This work plans to explore a new strategy to enhance the corrosion resistance of graphene coating by combining the molecular modification technique and graphene-polymer composite process. Firstly, the influences of electrical and electrochemical properties on the corrosion promotion effects are systematically investigated in order to elucidate the corrosion promotion mechanism of graphene. Previous work has proved that the corrosion promotion effect is closely related to electrical conductivity and electrochemical reactivity. Consequently, fluorination as a molecular modification strategy is introduced to control the electrical conductivity and electrochemical reactivity of graphene.This work aims to detailedly illustrate the close relationship among the bonding structure, electrochemical reactivity and electrical conductivity of graphene, thus giving the effective measures to inhibit this effect from the molecular aspect. Finally, the coating structure and process parameters are optimized to obtain corrosion resistant composite coating with high thermal conductivity and hydrophobility for enhancing the heat transfer process. It not only provides a theoretical base for developing superior anticorrosive graphene coating with thermal conductivity, but also is of great significance to solve the corrosion problem during heat energy reclaim.
