摘要

氧化石墨烯(GO)由许多含氧官能团组成,这些官能团有助于对其进行化学修饰。因此,我们探索了正丁胺(nBA)功能化 GO(即 GO-nBA)的合成和在酸化环境(15% HCl)中对 N80 钢的缓蚀应用。核磁共振和透射电镜对 GO-nBA 进行了表征。在表面检测技术的支持下,通过化学和电化学方法对 GO-nBA 的性能进行了评估。PDP 结果表明,GO-nBA 具有混合保护能力。此外,93.93 % 的效率值也证实了 GO-nBA 的卓越性能。表面研究进一步表明,加入 GO-nBA 后,表面纹理变得光滑。计算分析表明,GO-nBA 具有出色的抑制性能。

Graphene oxide composite as a novel corrosion inhibitor for N80 steel in 15 % HCl: experimental and quantum chemical examinations
Graphene oxide (GO) consists of many functional groups containing oxygen that helps in its chemical modifications. Thus, we have explored the synthesis, and corrosion inhibition application of n-butylamine (nBA) functionalized GO, i.e., GO-nBA for N80 steel in the acidizing environment (15 % HCl). NMR and TEM characterized the GO-nBA. The performance of GO-nBA was evaluated via chemical and electrochemicals methods that are supported by surface examination techniques. The PDP results supports the mixed nature of protection ability of GO-nBA. Additionally, the excellency of GO-nBA is confirmed by the value of 93.93 % efficiency. The surface study furthermore represents smooth texture with the addition of GO-nBA. The computational analysis reveals excellent inhibitive performance of GO-nBA.
