Considering the problem of icing in civil aircraft flying at high altitudes and in cold areas, the com-posite coating was prepared by doping a certain content of carbon nanotubes (CNT) in Epoxy resin (Ep), which optimised and improved the de-icing performance of civil aircraft. At the same time, the anti-corrosion performance of the CNT-modified Ep on the wing skin was investigated. The test shows that when the CNT content is 0.5%, the photothermal performance of the composite is good, and the temperature rise is obvious. The photothermal cycling stability test shows that when the CNT content is 0.5%, the composite coating has photothermal stability under 150 (mW·cm-2) light. The self-healing performance analysis test shows that after a certain degree of surface damage, the compo-site coating can achieve self-healing by heating. In the polarisation curve analysis of the electrochemi-cal station (CHI660E) test, the maximum corrosion potential of the composite coating with 0.5% CNT content is -1.510 V, indicating the lowest corrosion rate compared to others. In the static full immersion test, the composite coating with 0.5% CNT content is reduced the least, indicating its good corrosion resistance.
