为解决二氧化钛/硫化镉(TiO2/CdS)复合材料作为光生阴极防腐保护材料无法对金属提供持久性光生阴极保护、导电率低和载流子复合率高等问题，引入氧化石墨烯(GO)和聚苯胺(PANI)材料，通过水热法和原位聚合法制备了TiO2/CdS/GO/PANI复合材料，将其作为改性环氧树脂涂层，制备出兼具优异光电转换性能和防腐性能的双功能环氧树脂基涂层。通过对Q235碳钢(Q235 CS)表面进行涂覆，研究了复合涂层的光生阴极保护电化学性能和防腐性能参数。结果表明，TiO2/CdS/GO/PANI修饰后的环氧树脂基涂层表现出优异的光电化学性能和防腐性能，光电流密度达到0.15 A/cm2,开路电位为-0.8 V,防腐蚀效率高达98.55%。
Abstract：To solve the problems that titanium dioxide/cadmium sulfide(TiO2/CdS) composites as photogenerated cathodic corrosion protection materials cannot provide durable photogenerated cathodic protection for metals, and have low electrical conductivity and high carrier recombination rate, graphene oxide(GO) and polyaniline(PANI) materials were introduced, and TiO2/CdS/GO/PANI composites were prepared by hydrothermal method and in situ polymerization method. With TiO2/CdS/GO/PANI composites as the modified epoxy resin coating, a bifunctional epoxy resin-based coating with both excellent photoelectric conversion performance and anti-corrosion performance was prepared. By coating the surface of Q235 carbon steel(Q235 CS), the photogenerated cathodic protection electrochemical performance and anticorrosion performance parameters of the composite coating were investigated. The results show that the TiO2/CdS/GO/PANI modified epoxy resin-based coating exhibits excellent photoelectrochemical performance and anticorrosion performance, the photocurrent density resches 0.15 A/cm2, the open-circuit potential is-0.8 V, and the anticorrosion efficiency is high, up to 98.55%.
