A facile and cost-effective preparation of moisture-responsive graphene bilayer paper by focused sunlight irradiation is reported. The smart graphene paper shows moisture-responsive properties due to selective adsorption of water molecules, leading to controllable actuation under humid conditions. In this way, graphene-based moisture-responsive actuators including a smart claw, an orientable transporter, and a crawler paper robot are successfully developed.
本文报道了一种简便、经济的方法，通过聚焦阳光照射制备对湿度响应的双层石墨烯纸。智能石墨烯纸由于水分子的选择性吸附而表现出对湿度响应的特性，从而在潮湿条件下实现可控致动。以此为基础，成功研制了基于石墨烯的湿度响应致动器，包括智能爪子、可转向传输器和爬行纸机器人。
