Increasing the mechanical durability of large‐area polycrystalline single‐atom‐thick materials is a necessary step toward the development of practical and reliable soft electronics based on these materials. Here, it is shown that the surface assembly of organosilane by weak epitaxy forms nanometer‐thick organic patches on a monolayer graphene surface and dramatically increases the material's resistance to harsh postprocessing environments, thereby increasing the number of ways in which graphene can be processed. The nanopatched graphene with the improved mechanical durability enables stable operation when used as transparent electrodes of wearable strain sensors. Also, the nanopatched graphene applied as an electrode modulates the molecular orientation of deposited organic semiconductor layers, and yields favorable nominal charge injection for organic transistors. These results demonstrate the potential for use of self‐assembled organic nanopatches in graphene‐based soft electronics.

纳米修补石墨烯与石墨烯-有机混合软电子分子自组装

提高大面积多晶单原子厚材料的机械耐久性是基于这些材料开发实用，可靠的软电子器件的必要步骤。在此表明，通过弱外延进行有机硅烷的表面组装可在单层石墨烯表面上形成纳米级的有机补丁，并显着提高了材料对苛刻后处理环境的抵抗力，从而增加了石墨烯的加工方式数量。当用作可穿戴应变传感器的透明电极时，具有改善的机械耐久性的纳米修补石墨烯可实现稳定的操作。此外，用作电极的纳米修补石墨烯可调节沉积的有机半导体层的分子取向，并为有机晶体管产生有利的标称电荷注入。这些结果证明了在基于石墨烯的软电子产品中使用自组装有机纳米补丁的潜力。
