石墨烯氧化物（GO）与水分子之间的强烈相互作用引发了对开发基于GO的分离膜，传感器和致动器的巨大研究兴趣。然而，对GO板之间的超快水传输的复杂控制以及随后整个GO膜的变形仍然是具有挑战性的。受到自然“量子隧穿-流体效应”的启发，这里报道了通过单侧引入周期性光栅来实现GO纸的量子限制-超流体的湿度驱动。折叠的GO纳米片充当量子限制超流体通道，可以显著促进水的吸附，实现可控和灵敏的水分驱动。从理论上和

石墨烯氧化物（GO）与水分子之间的强烈相互作用引发了对开发基于GO的分离膜，传感器和致动器的巨大研究兴趣。然而，对GO板之间的超快水传输的复杂控制以及随后整个GO膜的变形仍然是具有挑战性的。受到自然“量子隧穿-流体效应”的启发，这里报道了通过单侧引入周期性光栅来实现GO纸的量子限制-超流体的湿度驱动。

折叠的GO纳米片充当量子限制超流体通道，可以显著促进水的吸附，实现可控和灵敏的水分驱动。从理论上和实验上研究了沿着和逆着GO纸的法线方向的水吸附引起的膨胀。智能GO纸具有最先进的超快响应（1.24 cm-1 s-1），大变形程度，复杂且可预测的变形，用于仿生小型机器人，包括爬行蜈蚣和智能叶片那可以抓住活着的瓢虫。

总之，该研究报道的方法对于2D材料来说简单且通用，揭示了开发基于石墨烯的智能机器人的巨大潜力。
