摘要:

綜述了自修復防腐涂層的研究進展，將現有自修復防腐涂層的體系分為兩種：一種是通過在涂層內包埋成膜物質或緩蝕劑實現涂層缺陷修復的自主型修復機制，另一種則是以溫度、光等外界條件刺激響應實現涂層缺陷修復的非自主型修復機制。自主型和非自主型修復機制相互結合，實現涂層防護性能和功能性的長效修復，將會是未來自修復防腐涂層發(fā)展的主要方向。

Abstract:

The research progress of self-healing anti-corrosion coatings and classifies the existing self-healing anti-corrosion coating systems into two kinds. One is by embedding the film-forming material or corrosion inhibitor in the coating to achieve the autonomous repair of the coating’s anti-corrosion property. The other is the non-autonomous mechanism that uses temperature, light or other external stimulus to achieve the repair of coating defects. The combination of the autonomous and non-autonomous healing mechanisms to achieve long-term repair performance over the anti-corrosion and functional properties of the coating will be the direction of development of next-generation self-healing coatings for corrosion protection.
