将含有纤维素纳米纤维的聚合物涂层应用于碳钢以用于缓蚀。用刀口刮擦试样，然后在氯化钠溶液中监测极化电阻。含有纳米纤维和缓蚀剂的划痕试样的极化电阻高于仅含有缓蚀剂的聚合物涂层的极化电阻。纤维素纳米纤维缓蚀剂的最佳配比为4。在腐蚀测试后，在聚合物涂层的横截面上确认了空孔，这表明纳米纤维充当了用于释放腐蚀抑制剂的途径。(C)2014爱思唯尔有限公司版权所有。
Polymer coatings containing cellulose nanofibers were applied to carbon steel for corrosion inhibition. The specimens were scratched with a knife-edge, and then polarization resistance was monitored in a sodium chloride solution. The polarization resistance of the scratched specimen containing nanofibers and corrosion inhibitor was higher than that of a polymer coating that contained only a corrosion inhibitor. The optimal mixing ratio of corrosion inhibitor for cellulose nanofibers was 4. Empty holes were confirmed on a cross-section of the polymer coating after the corrosion test, which showed that the nanofibers served as pathways for the release of the corrosion inhibitor.
