摘要

近年来，随着微型化和新型功能化的发展，人们对微胶囊进行了研究。在这项工作中，我们设计并制备了一系列独特的具有刺激响应功能的形状记忆聚氨酯（SMPU）微胶囊。微胶囊具有可调节表面形态的核壳结构，具有一定的承载能力。此外，SMPU微胶囊具有形状记忆和溶剂反应的刺激响应功能。其形状恢复的温度约为体温，在有机溶剂的刺激下可膨胀至破裂。因此，SMPU微胶囊在药物释放等生物医学领域具有潜在的应用前景。图形摘要

Adjustable volume and loading release of shape memory polymer microcapsules

ABSTRACT Research on microcapsules has been conducted in recent years given trends in miniaturization and novel functionalization. In this work, we designed and prepared a series of unique shape memory polyurethane (SMPU) microcapsules with stimuli-responsive functions. The microcapsule has a core-shell structure in which the surface morphology can be adjusted, and it has a certain load-bearing capacity. In addition, the SMPU microcapsule has a stimuli-responsive function for shape memory and solvent response. The temperature of its shape recovery is approximately body temperature, and it can swell to rupture under the stimulation of organic solvents. Thus, the SMPU microcapsule has potential applications in biomedical fields, such as drug release. GRAPHICAL ABSTRACT
