Self-healing polymer coatings made up of different concentrations of cellulose nanofibers and zeolite particles were investigated for the ability to effectively release corrosion inhibitor. The electrochemical impedances of scratched specimens were monitored in a corrosive solution. The release behavior of corrosion inhibitor was measured via mass changes in a polymer sheet. Coatings containing both cellulose nanofibers and zeolite particles led to large and sustained releases of corrosion inhibitor. Increases in the zeolite particles connected to cellulose nanofibers increased the pH, which led to a two-step release of corrosion inhibitor that was aided by the nanofibers that served as pathways.

研究了由不同浓度的纤维素纳米纤维和沸石颗粒组成的自修复聚合物涂层有效释放腐蚀抑制剂的能力。在腐蚀性溶液中监测划痕样品的电化学阻抗。通过聚合物片材的质量变化来测量腐蚀抑制剂的释放行为。同时包含纤维素纳米纤维和沸石颗粒的涂层导致腐蚀抑制剂大量持续释放。与纤维素纳米纤维连接的沸石颗粒的增加增加了pH，这导致了缓蚀剂的两步释放，而缓蚀剂是通过作为路径的纳米纤维来辅助的。
