Synergetic self-healing anticorrosion behaviors, by forming a self-assembly protective layer and repairing coating passive barrier, exhibit great potential in handling the notorious metal corrosion phenomenon. Herein, we developed nanofiber-supported with synergistic protection effects of both active inhibition, via facile electrospinning combined technique. Polycaprolactone (PCL) nanofiber integrated 2-mecapobenzothiazole-loaded halloysite nanotubes (HNTs-MBT) is directly deposited on surface substrate, an interconnected fiber network framework. The encapsulated inhibitor MBT can be released pH-triggered manner to realize instant protections. Additionally, defects could repeatedly repaired continuous polymer upon heat treatment efficiency effectively remained, even after three cycles damage-healing. Moreover, also exhibited durable performance, mainly attributed synergetic thermal-triggered bulk healing inhibition. This type dual-functional provides efficient anticorrosive performances may show promise long-term protection.
