由于CFRP具有良好的导电性能和耐腐蚀性，将CFRP用于加固混凝土柱同时兼作阴极保护的阳极材料，实现补强加固和阻止钢筋锈蚀的双重目的。其思路是采用导电性胶把CFRP粘贴到混凝土柱表面，CFRP作为阳极，钢筋作为阴极，通过外部直流电源设备给钢筋持续施加一定密度的电流从而使得在钢筋上的阳极反应降低到最小程度，抑制钢筋的锈蚀；同时，CFRP约束作用能显著提高柱承载力和抗震性能，充分发挥CFRP的优点。本项目采用溶液共混法将纳米石墨片添加到聚合物基体中制备导电胶粘剂，系统研究不同纳米石墨片掺量对导电胶导电性能、力学性能、粘接性能和耐久性能的影响规律；确定能满足加固和阴极保护用导电胶的合理配比。在此基础上，研究采用导电胶粘贴CFRP加固混凝土柱的阴极保护特性，分析极化电阻、电荷转移电阻等参数的变化规律，钢筋表面锈蚀产物的物相组成和钢筋/混凝土界面形貌，揭示CFRP加固混凝土柱的阴极保护机制。

Carbon fiber reinforced polymer (CFRP) used for strengthening RC column is also used as an anode of cathodic protection because of their excellent electrically conductive. The aim of this design can achieve strengthening as well as protection of steel rebar. The CFRP bonded onto the RC column used conductive adhesive is used as anode. The reinforcing steel rebar is used as cathode. An external DC power is used to impress the constant required for the cathodic protection. The CFRP wrapped RC column can improve both load capacity and seismic performance. Graphite nanoPlatelets (GNPs)/epoxy adhesive composite is prepared by liquid mixing method. The electrical conductivity, mechanical properties and durability performance of GNPs/epoxy adhesive composite are investigated with a series of tests, the effect of GNPs content on electrical conductivity, mechanical properties and durability are analyzed, and optimal design is determined. Polarization resistance, charge transfer resistance and the half-cell potential of steel are reported as metrics of performance of the samples. X-ray diffraction (XRD) combined with scanning electron microscopy (SEM) is applied for microstructural analysis of corrosion products and steel/concrete interface. Mechanism of cathodic protection for CFRP wrapped around RC column is explored.
