We develop hetero-nanostructured black phosphorus/metal-organic framework hybrids formed by P-O-Co covalent bonding based on a designed droplet microfluidic strategy consisting of confined and ultrafast microdroplet reactions. The resulting hybrid exhibits large capacitance (1347 F g ) in KOH electrolytes due to its large specific-surface-area (632.47 m g ), well-developed micro-porosity (0.38 cm g ), and engineered electroactivity. Furthermore, the proposed 3D printing method allows to construct all-integrated solid-state supercapacitor, which maintains interconnected porous network, good interfacial adhesion, and robust flexibility for short-path diffusion and excessive accommodation of ions. Consequently, the fabricated flexible supercapacitor delivers ultrahigh volumetric energy density of 109.8 mWh cm , large capacitance of 506 F cm , and good long-term stability of 12000 cycles.
我们基于一种由受限和超快微滴反应组成的设计微流控策略，开发了通过P-O-Co共价键形成的异质纳米结构黑磷/金属有机框架杂化物。由于其大比表面积（632.47 m² g⁻¹）、发达的微孔率（0.38 cm³ g⁻¹）和工程化的电活性，所得杂化物在KOH电解质中表现出大电容（1347 F g⁻¹）。此外，所提出的3D打印方法能够构建全集成固态超级电容器，该超级电容器保持相互连接的多孔网络、良好的界面粘附性以及用于离子短程扩散和过度容纳的强大柔韧性。因此，所制备的柔性超级电容器具有109.8 mWh cm⁻³的超高体积能量密度、506 F cm⁻³的大电容以及12000次循环的良好长期稳定性。
