摘要: 

通过原位化学氧化合成法制备了含不同比例纳米TiO2的聚苯胺/TiO2复合粉.以环氧树脂为成膜物质,采用共混的方法制备了聚苯胺/TiO2/环氧涂层,并通过正交实验优选出了力学性能最佳的涂层配方,耐化学品性测试验证了优选配方同时具有最佳的耐蚀性.最后分别考察了优选配方涂层在含S2-及Cl-盐溶液中的耐蚀性.结果表明:合成的复合粉颗粒为纳米级,聚苯胺和TiO2存在强烈相互作用;正交实验各因素对涂层力学性能影响的重要程度次序为:聚苯胺>TiO2>固化温度>溶剂的量>溶剂间比例;当聚苯胺与环氧树脂质量比为1∶100,TiO2与环氧树脂质量比为1∶100,固化温度为60 ℃,溶剂的量与环氧树脂质量比为5∶10,NMP与正丁醇的溶剂摩尔比为2∶1时,所得涂层力学性能及耐蚀性能最佳;涂层在65 ℃,3.5% (质量分数) NaCl溶液中浸泡72 h后电化学阻抗出现极大值,在80 ℃,3% (质量分数) Na2S溶液中浸泡120 h仍然具有良好的耐蚀性.

Abstract：

Polyaniline/TiO2 nano composites with different weight ratios of polyaniline to TiO2 were synthesized using chemical oxidative polymerization through polymerizing polyaniline (PANI) onto the nano TiO2 surface. The prepared PANI/TiO2 composites were characterized by FTIR, XRD and SEM. Then PANI/TiO2/epoxy resin coating was prepared by blending epoxy resin with polyaniline/TiO2 nano powders, while coating formulation with excellent mechanical performance was acquired through orthogonal experiments and trial corrosion tests. The corrosion performance of X70 steel coated with the optimal coating was examined in S2- and Cl- containing solutions at different temperatures. The results show that there exists strong interaction between the nano TiO2 particle and PANI within the PANI/TiO2 composites. Many factors could affect the mechanical property of the coatings, according to their impact degree, which may be ranked as the following sequence: PANI>TiO2>curing temperature>solvent content>solvent ratio. The optimal PANI/TiO2/epoxy resin coating with excellent mechanical properties and corrosion performance could be acquired by an optimal process with the following parameters: the mass ratio of PANI to epoxy resin is 1 to 100; TiO2 to epoxy resin is 1 to 100; curing at 60 ℃. The content of solvent to epoxy resin is 5 to 10 and NMP/n-butanol=2/1(solvent molar ratio). Furthermore, at 72 h after immersion of the optimal coating in 3.5%NaCl solution at 65 ℃, a maximum appeared on its impedance vs time curve, whilst the coating keeps an excellent corrosion resistance even after immersion in 3%Na2S solution for 120 h at 80 ℃.
