摘要：分别以十二烷基硫酸钠（SDS）和木质素磺酸钠（LGS）为掺杂剂，通过化学氧化法合成了两种磺化聚
苯胺（PANI-SDS 和 PANI-LGS），并将合成的磺化 PANI 混入溶胶-凝胶法制备的硅树脂（SiR）中，刷涂在 Q235
钢表面制备了复合防腐蚀涂层。采用 FTIR 表征了磺化 PANI 的结构；对比了 PANI-LGS 和 PANI-SDS 的基本性
能，考察了 SiR、PANI-SDS/SiR 和 PANI-LGS/SiR 复合涂层的耐水性、附着力、机械性能及防腐蚀性能，并分
析了复合涂层的防腐蚀机理。结果表明：制备的 PANI-LGS/SiR 复合涂层疏水性能较好，接触角达到 113.0º，
吸水率仅为 7.58%。电化学测试结果表明，该复合涂层对 Q235 钢具有良好的防腐蚀性能，腐蚀速率为 5.56×

Abstract: Two kinds of sulfonated polyanilines, PANI-SDS and PANI-LGS were synthesized by chemical
oxide method with sodium dodecyl sulfate (SDS) and sodium lignosulfonate (LGS) as dopant, respectively,
followed by mixed with silicone resin (SiR) prepared by sol-gel method, and then coated on the surface of
Q235 steel to prepare composite aniticorrosion coatings. The structures of sulfonated PANI were
characterized by FTIR. The basic properties of PANI-SDS and PANI-LGS were compared. The
hydrophobicity, adhesion, mechanical properties and anticorrosion properties of SiR, PANI-SDS/SiR and
PANI-LGS/SiR composite coatings were investigated. The anticorrosion mechanism of the composite
coating was analyzed. The results showed that PANI-LGS/SiR composite coating had better hydrophobic
property. The water contact angle of the coating was 113.0°, and the water absorption was only 7.58%.
Electrochemical test results showed that the composite coating had better corrosion resistance to Q235 steel.

The corrosion rate was 5.56×10 mm/a. PANI-LGS/SiR composite coating provided protection to Q235
steel against corrosion by the effect of physical barrier and anodic protection.
