摘要

在实际应用中,除防腐外,聚氨酯涂料的抗紫外线性能也极为重要。以植酸(PA)为掺杂剂,在酸性环境下在F-d@CeO2表面原位生成氟化聚苯胺(FPANI), FT-IR、Raman、TG、XRD和XPS测试表明,氟化聚苯胺与聚多巴胺形成化学键合。防腐实验表明,当填料含量(FPANIPA/F-d@CeO2)为5 wt%时,复合涂层(PFC5)的防腐性能最佳。浸泡120 d后,PFC5复合涂层的|Z|0.01 Hz保持在108 Ω·cm2以上。另一方面,氧化铈具有吸收和保护紫外线的能力,氟化聚苯胺和聚多巴胺的自由基清除能力可以捕获紫外线老化聚氨酯产生的自由基,抑制或阻断涂层的光氧化反应。因此,PFC5复合涂层表现出优异的抗紫外线性能,紫外线老化300 h后光氧化指数和羰基指数最低,并保持优异的耐腐蚀性和力学性能。同时,POM、EIS和力学性能测试表明,PFC5复合涂层具有优异的光热自愈性能,自愈前后涂层仍保持良好的力学性能和防腐性能,自愈效率达90%以上。

One stone three birds: hydrophobic, self-healing and UV-resistant polyurethane composite coating based on FPANI@CeO2 for anti-corrosion applications
In practical applications, the UV resistance of polyurethane coatings is extremely important in addition to the corrosion protection. Fluorinated polyaniline (FPANI) was generated in situ on the surface of F-d@CeO2 in an acidic environment using phytic acid (PA) as a dopant, and FT-IR, Raman, TG, XRD, and XPS tests showed that the fluorinated polyaniline was chemically bonded to polydopamine. Anti-corrosion experiments showed that the composite coating (PFC5) with the best anti-corrosion properties was when the filler content (FPANIPA/F-d@CeO2) was 5 wt%. The |Z|0.01 Hz of the PFC5 composite coating remained above 108 Ω·cm2 after 120 d of immersion. Cerium oxide, on the other hand, has the ability to absorb and protect from UV light, and fluorinated polyaniline and polydopamine’s free radical scavenging capabilities can trap the free radicals generated by UV-aging polyurethane and inhibit or block the photo-oxidation reaction of the coating. Therefore, the PFC5 composite coating shows excellent UV resistance, with the lowest photo-oxidation index and carbonyl index after UV aging for 300 h, and maintains excellent corrosion resistance and mechanical properties. At the same time, the tests of POM, EIS and mechanical properties show that the PFC5 composite coating exhibits excellent photothermal self-healing performance, and the coating still maintains good mechanical properties as well as anticorrosion properties before and after self-healing, with a self-healing efficiency of more than 90 %.
