中文摘要:
      以苯胺(AN)和间氨基酚(mAP)为单体,乙酸(AcOH)与对甲氧基苯乙酸(MOPAc)为掺杂酸,Fenton(Fe2+/H2O2)试剂为引发剂,合成了AcOH-PANI、AcOH-PmAP、MOPAc-PmAP、MOPAc-PANI体系防腐纳米材料。采用FTIR、UV-vis、XRD、SEM及粒度分布对聚合物防腐材料的形貌、结构进行了表征。结果表明:利用对甲氧基苯乙酸为掺杂酸制备出的聚合物粒径分布均匀且溶解度好。电化学测试表明:该聚合物为阴极为主的混合型缓蚀剂,且缓蚀效率遵循:MOPAc-PmAP > AcOH-PmAP > MOPAc-PANI > AcOH-PANI。MOPAc-PmAP,AcOH-PmAP与吐温80 (Tween80) 复配的电化学测试结果表明:当缓蚀剂浓度为100 mg/L,吐温80浓度为50 mg/L时,MOPAc-PmAP-Tween80体系防腐效果最佳,相比未添加Tween80的样品(71.04%)缓蚀效率高达96.05%。说明MOPAc-PmAP与吐温80表现出了优异的协同作用。
英文摘要:
      A series of anti-corrosion nanomaterials, AcOH-PANI, AcOH-PmAP, MOPAc-PmAP and MOPAc-PANI were synthesized by using aniline (AN) and m-aminophenol (mAP) as monomers, acetic acid (AcOH) and p-methoxyphenylacetic acid (MOPAc) as doped acids, Fenton (Fe2+/H2O2) reagent as initiator. The morphology and structure of the polymer materials were characterized by FTIR, UV-vis, XRD, SEM and particle size analyzer. The results showed that the polymer prepared by using p-methoxyphenylacetic acid as doped acid had uniform particle size distribution and good solubility. Electrochemical tests suggested that the polymer was a cathode-based mixed corrosion inhibitor, and the corrosion inhibition efficiency followed the order MOPAc-PmAP > AcOH-PmAP > MOPAc-PANI > AcOH-PANI. MOPAc-PmAP and AcOH-PmAP, in presence of Tween80, showed better anticorrosion properties. Especially when the concentration of corrosion inhibitor was 100 mg/L and that of Tween80 was 50 mg/L, the system of MOPAc-PmAP-Tween80 had the outstanding corrosion inhibition efficiency as high as 96.05%, which was higher than the system in absence of Tween80 (71.04%), indicating that there was excellent synergism between MOPAc-PmAP and Tween80.
