【摘要】:采用直接混合法,在酒石酸體系下合成一次摻雜聚苯胺納米材料,經(jīng)氨水解摻雜后,再用單寧酸對其進行二次摻雜制備出單寧酸二次摻雜聚苯胺材料,解決了單寧酸體系下苯胺無法有效聚合制備聚苯胺的難題。通過掃描電鏡、紅外光譜及紫外光譜測試對產(chǎn)物進行了表征,利用電化學(xué)工作站測試了不同聚苯胺薄膜對Q235碳鋼的防腐蝕性能。結(jié)果表明,通過二次摻雜方法,單寧酸能有效地?fù)诫s到聚苯胺中,獲得形貌良好的納米纖維;單寧酸二次摻雜聚苯胺能較長時間有效地保護金屬基材,其防腐蝕效率最高可達86.02%,在天然海水中浸泡7 d后仍能保持在78.84%。
[Abstract]:Polyaniline nano-materials were synthesized by direct mixing method in tartaric acid system. After ammonia hydrolysis and doping, tannic acid was used to dope the nano-materials to prepare polyaniline. The problem that aniline can not be effectively polymerized in tannic acid system was solved. Polyaniline was prepared by scanning electron microscopy and infrared spectroscopy. The results show that tannic acid can be effectively doped into polyaniline to obtain nanofibers with good morphology by the secondary doping method, and the secondary doping of tannic acid with polyaniline can be effective for a long time. The corrosion protection efficiency of the ground-protected metal substrate is up to 86.02% and can still be maintained at 78.84% after soaking in natural seawater for 7 days.
