摘　　要：在酒石酸体系中研究不同合成方法、酒石酸浓度、反应温度、反应时间等因素对制备聚苯胺纳米纤维的影响,通过扫描电镜(SEM)、红外光谱(FT-IR)及紫外光谱(UV-Vis)测试技术对产物进行了表征,测定了不同方法制备产物在N-甲基吡咯烷酮中溶解性能,并采用电化学测试技术研究了产物的防腐性能。结果表明,直接混合法是一种简便高效的聚合方法,可制备高品质聚苯胺;最佳合成条件为酒石酸0.1mol/L、温度20℃、反应时间24h。直接混合法制备产物,其溶解性与缓慢滴加法产物相近,高于界面聚合法产物,为4.7g/L,防腐蚀效率优于缓慢滴加法和界面聚合法产物,达到87.79%。The effects of different synthesis methods,tartaric acid concentration,temperature,and time on the preparation of PANI nanofibers in tartaric acid system were studied in this paper.The products were characterized by the testing technique of scanning electron microscope(SEM),Fourier transformed infrared spectroscopy(FT-IR)and Ultraviolet and visible spectrum(UV-Vis).The solubility in NMP system and corrosion resistance of the PANI prepared with different methods were also investigated.The results showed that direct mixing reaction is a simple and efficient polymerization method for fabricating high quality PANI.The optimum preparation parameters of direct mixing method are as follows:tartaric acid 0.1mol/L,20℃,24 h.The solubility of PANI with direct mixing reaction is 4.7g/L,similar to the dripping slowly reaction,but higher than that of PANI prepared with interfacial polymerization.The inhibition efficiency of PANI prepared with direct mixing method is 87.79%,which is much better than that of PANI prepared with the dripping slowly reaction and interfacial polymerization.
