摘要：Self-healing polymers are categorised as smart materials which are capable of surface protection and prevention of structural failure. Polyurethane/polyurea as one of the representative coatings has also attracted industrial applications. Comparing with polyurethane, polyurea coating with the similar formation progress indicates higher tensile strength and shorter curing time. In this paper, the extrinsic and intrinsic mechanism are reviewed to address the efficiency of self-healing progress. Moreover, the formulation optimization and strategic improvement to ensure the self-healing within a shorter period of time with acceptable recovery of mechanical strength are also discussed. The choice and ratio of diisocyanate as well as the choice of chain extender are believed to have the crucial effect on the acceleration of self-healing process and enhance self-healing efficiency during the preparation of polyurea coatings.
