Properly cut sheets can be converted into complex 3D structures by three basic operations including folding, bending, and pasting to render new functions. Folding and bending are extensively employed in crumpling, origami, and pop‐up fabrications for 3D structures. Pasting joins different parts of a material together, and can create new geometries that are fundamentally unattainable by folding and bending. However, it has been much less explored, likely due to limited choice of weldable thin film materials and residue‐free glues. Here it is shown that graphene oxide (GO) paper is one such suitable material. Stacked GO sheets can be readily loosened up and even redispersed in water, which upon drying, restack to form solid structures. Therefore, water can be utilized to heal local damage, glue separated pieces, and release internal stress in bent GO papers to fix their shapes. Complex and dynamic 3D GO architectures can thus be fabricated by a cut‐and‐paste approach, which is also applicable to GO‐based hybrid with carbon nanotubes or clay sheets.

一种基于3D石墨烯氧化物的架构的剪切粘贴方法

可以通过三个基本操作（包括折叠，弯曲和粘贴以呈现新功能）将正确裁切的图纸转换为复杂的3D结构。折叠和折弯广泛用于3D结构的折皱，折纸和弹出式制作中。粘贴将材料的不同部分连接在一起，并且可以创建从根本上无法通过折叠和弯曲获得的新几何形状。但是，由于可焊接薄膜材料和无残留胶水的选择有限，因此尚未对其进行深入研究。在此表明，氧化石墨烯（GO）纸就是这样一种合适的材料。堆积的GO板很容易松散，甚至可以重新分散在水中，干燥后再堆积成固体结构。因此，可以利用水来修复局部损伤，胶合分离的碎片，并释放弯曲的GO纸中的内部应力以固定其形状。因此，可以通过剪切粘贴方法来制造复杂且动态的3D GO体系结构，该方法也适用于具有碳纳米管或粘土板的基于GO的混合体。
