Stimuli responsiveness has long been a fascinating feature of smart material design. Polydopamine (PDA), a nature inspired polymeric pigment, exhibits excellent photo-responsive properties and has active surface functionality for loading various responsive motifs, making it a promising candidate for the construction of stimuli-responsive smart functional materials. PDA has long been considered as a robust coating material, but its responsive feature has rarely been emphasized in the past reviews. Herein, we present the first effort to summarize recent advances in the design strategies, responsive mechanisms, and diverse applications of stimuli-responsive PDA-based smart materials; the stimuli include light, pH, chemicals, temperature, humidity, electric fields, mechanical force, magnetic fields, and ultrasound. Moreover, the current trends, challenges, and future directions of stimuli-responsive PDA-based materials are also elaborated.
刺激响应性一直是智能材料设计引人入胜的特征。聚多巴胺（PDA）是一种受自然启发的聚合物颜料，具有优异的光响应性能和用于负载各种响应性图案的活跃表面功能，使其成为构建刺激响应智能功能材料的有前途的候选材料。PDA 长期以来一直被认为是一种坚固的涂层材料，但过去的评论很少强调其响应特性。在此，我们首次努力总结了基于刺激响应性 PDA 的智能材料的设计策略、响应机制和各种应用的最新进展；刺激包括光、pH 值、化学物质、温度、湿度、电场、机械力、磁场和超声波。此外，还阐述了基于刺激响应性 PDA 的材料的当前趋势、挑战和未来方向。
