Stimuli-responsive elastic organogels have a potential for functional sensors and actuators. However, it remains a challenge to prepare an organogel actuator that can be driven by in situ swelling to generate controlled shape morphing and maintain its kinematic activities with consecutive sorption/desorption of organic solvents. Here, we report a stretchable (strain, 130%), robust (stress, 7.0 MPa), and elastic organogel that is synthesized through ring-opening polymerization of a long-chain epoxide monomer into a crosslinking fluoro-network (CFN). The structure results in the organogel being capable of absorbing polar organic solvents (maximum swellability: 178% ± 10%) and generating indefatigable shape morphing. The in situ swelling (no diffusion) of organic droplets can induce shape morphing in a controllable manner, without the assistance of any structural designs, such as surface patterning, bilayer structures, and origamis. A series of kinematics tests demonstrate that the CFN organogel has a potential for chemical sensing devices.

刺激响应性弹性有机凝胶具有功能性传感器和执行器的潜力。然而，制备有机凝胶致动器仍然是一个挑战，该有机凝胶致动器可以通过原位溶胀来驱动以产生受控的形状变形并在连续吸收/解吸有机溶剂的同时保持其运动学活性。在这里，我们报告了一种可拉伸的（应变为130％），坚固的（应力为7.0 MPa）和弹性的有机凝胶，它是通过将长链环氧化物单体开环聚合成交联氟网络（CFN）来合成的。该结构使有机凝胶能够吸收极性有机溶剂（最大可溶胀性：178％±10％）并产生不变形的形状。在原位有机液滴的膨胀（不扩散）可以以可控的方式诱导形状变形，而无需任何结构设计的帮助，例如表面图案，双层结构和Origamis。一系列的运动学测试表明，CFN有机凝胶具有用于化学传感设备的潜力。
