Self‐healing materials have ability to repair damage by themselves. Their properties have been developed to increase the reliability of materials. Generally, self‐healing polymers have been developed by thermal polymerization. Especially, hydrogel materials showed relatively rapid recovery and goodhealing efficiency. However, it is very difficult to restore their properties without the self‐healing mediator such as water. Herein, we report the novel type of self‐healing polymer using photo‐polymerization. This is achieved through an unprecedented concept of an additive of photopolymerization, named as ‘healer’ which can act as a physical crosslinker between main chains and a self‐healing mediator in hydrogel materials. This transparent, easily fabricated self‐healing polymer healed scratch in 40 seconds as well as restored the mechanical properties to 82%.

新型光聚合添加剂的快速自修复膜。

自愈材料具有自行修复损坏的能力。已经开发出它们的特性以提高材料的可靠性。通常，可通过热聚合来开发自修复聚合物。特别地，水凝胶材料显示出相对快速的恢复和良好的修复效率。但是，如果没有自愈介质（例如水），则很难恢复其性能。本文中，我们报告了使用光聚合的新型自修复聚合物。这是通过前所未有的光聚合添加剂概念实现的，称为“修复剂”，可以充当水凝胶材料中主链和自修复介质之间的物理交联剂。这种透明的
