This work introduces an ultraviolet (UV)-curable elastomer through the co-polymerization of aliphatic polyurethane acrylate and hydroxypropyl acrylate via UV irradiation. The UV-curable elastomer presents superior mechanical properties (elongation at a break of 2992%) and high transparency (94.8% at 550 nm in the visible light region). A robust hydrogel-elastomer stretchable sensor is fabricated by coating an ionic hydrogel on the surface of an elastomer, which enables real-time monitoring of human motion. In addition, the UV-curable elastomer can be used for 3D printing, as demonstrated by complex lattice structures using a digital light processing 3D printer.
这项工作通过紫外线（UV）照射使脂肪族聚氨酯丙烯酸酯和羟丙基丙烯酸酯共聚，引入了一种可紫外线固化的弹性体。该可紫外线固化弹性体具有优异的机械性能（断裂伸长率达2992%）和高透明度（在可见光区域550nm处为94.8%）。通过在弹性体表面涂覆离子水凝胶制备了一种坚固的水凝胶-弹性体可拉伸传感器，能够实时监测人体运动。此外，如使用数字光处理3D打印机制作复杂晶格结构所示，该可紫外线固化弹性体可用于3D打印。
