Abstract

Spiral fibers with high energy storage and high output efficiency are highly desirable for soft robots and actuators. However, it is still a great challenge to achieve spiral fibers with excellent water actuation performance, structural stability, and high scalability in a low-cost strategy. A coaxial spiral structure is reported for the fabrication of high-performance fiber actuators. The developed shell–core helical fiber actuators were based on alginate/poly(ethylene glycol) acrylate shell and alginate/GO core with green and excellent spinnability. Owing to the high water-absorbing-swelling capacity and energy storage of the shell, the prepared spiral fibers are characterized by fast response, high energy output, and good repeatability of cycling. On the other hand, the core endows the spiral fibers with the additional features of strong force retention and photothermal response. The shell–core spiral structure promotes the output efficiency of the twisted fiber actuator with a large rotation (2500°/cm), untwisting speed (2250 rpm), and recovery speed (2700 rpm). In addition, the tertiary spiral structure based on TAPG fibers exhibits excellent humidity and photothermal response efficiency. The application of fibers to smart textiles enables efficient human epidermal thermal management.

采用壳核结构制备的水凝胶纤维致动器可实现高性能水/光双重响应

具有高能量存储和高输出效率的螺旋纤维是软机器人和致动器的理想之选。然而，如何以低成本策略实现具有出色的水驱动性能、结构稳定性和高可扩展性的螺旋纤维仍然是一个巨大的挑战。本文介绍了一种用于制造高性能纤维致动器的同轴螺旋结构。所开发的壳核螺旋纤维致动器以海藻酸盐/丙烯酸聚（乙二醇）酯为壳，海藻酸盐/GO 为核，具有绿色环保和优异的可纺性。由于外壳具有较高的吸水膨胀能力和储能能力，制备的螺旋纤维具有响应快、能量输出高和循环重复性好的特点。另一方面，纤芯赋予了螺旋纤维强力保持和光热响应的额外特性。壳-芯螺旋结构提高了加捻纤维致动器的输出效率，具有较大的旋转角度（2500°/cm）、解捻速度（2250 转/分钟）和恢复速度（2700 转/分钟）。此外，基于 TAPG 纤维的三级螺旋结构还具有出色的湿度和光热响应效率。将纤维应用于智能纺织品可实现高效的人体表皮热管理。
