摘　　要：生物软物质材料的特殊性能往往来源于其内部规整的有序结构。受此启发,在原本无规的水凝胶内部引入规整的内在本征结构有望赋予水凝胶各种独特的性能,使其作为多重刺激响应性智能材料在可视化生物传感器、机械形变诱导显示技术、软体机器人等新兴领域有着广泛的应用潜能。因此,制备具有一定内在有序结构的水凝胶已经成为水凝胶研究领域的一个新方向。在此基础上,结构化水凝胶(Structured hydrogel或Structural hydrogel)的概念被提出并逐步完善。文章结合笔者在结构化水凝胶领域的前期工作积累,从结构化水凝胶的基本概念、制备方法、特性以及应用等几个方面对结构化水凝胶的研究进展进行初步总结。Inspired by the regular internal structures found in many biological soft materials, which exhibit with unique functional performances, conventional hydrogels are expected to have enhanced functions through the incorporation of regular internal structures into their random and irregular polymeric matrix. With such synthesized hydrogels, numerous potential applications emerge, including but not limited to visible sensing,strain-induced visible displays, actuators, and soft robotics. Over the past decades, previous works have reported various types of hydrogels with internal regular structures, and the subfields of structured or structural hydrogels have gradually matured. This review briefly summarizes recent progress in structured hydrogels, focusing on the basic concepts, preparation strategies, and the unique properties conferred by internal structures.
