A novel near-infrared (NIR) light-responsive sodium polyacrylate (PAAS)/graphene oxide (GO) fiber with a torsional pre-deformation structure is reported to realize remote control actuation. The torsional pre-deformed PAAS/GO fiber exhibited various actuation phenomena, under the control of a low powered near-infrared light (50 mW cm), such as rotating in a low-temperature range (<25 °C), rolling a distance of 10 times of its diameter within 10 s, and even driving the shape change of a fabric (the weight is as high as 20 times of the fiber itself).
据报道，一种具有扭转预变形结构的新型近红外（NIR）光响应性聚丙烯酸钠（PAAS）/氧化石墨烯（GO）纤维可实现远程控制驱动。在低功率近红外光（50 mW/cm）的控制下，扭转预变形的PAAS/GO纤维表现出各种驱动现象，如在低温范围（<25°C）内旋转、在10秒内滚动其直径10倍的距离，甚至驱动织物的形状变化（织物重量高达纤维本身的20倍）。
