Covalent patterning of graphene opens many application possibilities in the field of photonics, electronics, sensors, and catalysis due to order-dependent optical properties, band structure engineering, and processibility and reactivity improvement. Owing to the low reactivity of the graphene basal plane, harsh reagents (e.g., radicals) used for covalent functionalization normally result in poor spatial control, which largely compromises the intrinsic properties of graphene. Therefore, precisely spatial control on covalent patterning of graphene is of great importance. Herein, we summarize recent advances for covalent patterning of graphene from the microscale to nanoscale resolution using different techniques such as laser or electrochemical writing, template-directed growth, and tip-induced nanoshaving.
由于与有序相关的光学性质、能带结构工程以及可加工性和反应活性的改善，石墨烯的共价图案化在光子学、电子学、传感器和催化领域开启了许多应用可能性。由于石墨烯基面的低反应活性，用于共价功能化的苛刻试剂（如自由基）通常会导致空间控制不佳，这在很大程度上损害了石墨烯的固有性质。因此，对石墨烯共价图案化进行精确的空间控制至关重要。在此，我们总结了使用不同技术（如激光或电化学写入、模板导向生长和针尖诱导纳米刮削）从微米级到纳米级分辨率对石墨烯进行共价图案化的最新进展。
