近年来，基于碳纳米管或石墨烯的致动材料已被广泛研究。然而，目前的碳基致动材料大多由单一刺激（湿度、光、电等）驱动，这意味着应用条件受到限制。本文提出了一种新型的多响应驱动材料，它可以由湿、光和电驱动，因此可以在各种条件下使用。制作是基于最简单的纸上铅笔的方法，其中铅笔和纸都是低成本和容易获得的日常材料。驱动效果更显着，由于一个双模式的驱动机制，这导致了一个超大的驱动（弯曲曲率高达2.6厘米（-1））。经过精心设计，该致动器还可以实现双向弯曲致动，这与以往报道的热致动器相比是一个显著的改进。利用纸张的可印刷特性和驱动器的多响应特性，制作了彩色仿生花和智能窗帘。据认为，新设计的驱动材料在纸上实验室设备，人工肌肉，机器人，仿生学和智能家居材料领域具有很大的潜力。
Recently, actuating materials based on carbon nanotubes or graphene have been widely studied. However, present carbon-based actuating materials are mostly driven by a single stimulus (humidity, light, electricity, etc.), respectively, which means that the application conditions are limited. Here, a new kind of multiresponsive actuating material which can be driven by humidity, light, and electricity is proposed, so it can be used in various conditions. The fabrication is based on the simplest pencil-on-paper method, in which the pencil and paper are both low-cost and easily obtained daily materials. The actuation effect is more remarkable due to a dual-mode actuation mechanism, which leads to an ultralarge actuation (bending curvature up to 2.6 cm(-1)). Elaborately designed, the actuator can further exhibit a bidirectional bending actuation, which is a significant improvement compared with previous reported thermal actuators. What is more, a colorful biomimetic flower and a smart curtain are also fabricated, fully utilizing the printable characteristic of the paper and multiresponsive characteristic of the actuator. It is assumed that the newly designed actuating material has great potential in the fields of lab-on-paper devices, artificial muscles, robotics, biomimics, and smart household materials.
