摘要

本研究评估了含有油酸（OA）的电纺醋酸纤维素纤维（CAF）在富氯环境中对碳钢的缓蚀效果。通过改变 OA 含量，生产出了不同厚度的 CAF。电位极化结果表明，涂有含 OA 的 CAFs 的钢具有更强的耐腐蚀性，腐蚀电位（Ecorr）更高，腐蚀电流密度（icorr）更低。浸涂样品的电化学阻抗光谱（EIS）结果显示，与未经处理的样品相比，阻抗增加了约 20 倍（从 2 kΩ cm2 增加到 40 kΩ cm2），电容从 10-6 F cm-2 降低到 10-8 F cm-2。即使暴露 48 小时后，保护效果依然存在。这些研究结果表明，CAFs 是输送 OA 抑制剂的有效载体，为缓解盐碱环境中的腐蚀问题提供了一种前景广阔的解决方案。

Cellulose acetate fibers as corrosion inhibitor delivery system for carbon steel

This study evaluated the effectiveness of electrospun cellulose acetate fibers (CAFs) containing oleic acid (OA) for corrosion inhibition on carbon steel in chloride-rich environments. By varying the OA content, CAFs of different thicknesses were produced. Potentiodynamic polarization showed that steel coated with OA-containing CAFs had enhanced corrosion resistance, with higher corrosion potential (E_corr) and lower corrosion current density (i_corr). The electrochemical impedance spectroscopy (EIS) results for the dip-coated sample showed an impedance increase of approximately 20× (from 2 to 40 kΩ cm²), and a capacitance reduction from 10⁻⁶ to 10⁻⁸ F cm⁻², compared to the untreated sample. The protective effect remained even after 48 h of exposure. These findings suggest CAFs as effective carriers for delivering OA inhibitors, offering a promising solution for corrosion mitigation in saline environments.
