Carbon nanofoam (CNF) is a highly porous, amorphous carbon nanomaterial that can be produced through the interaction of a high-fluence laser and a carbon-based target material. The morphology and electrical properties of CNF make it an ideal candidate for supercapacitor applications. In this paper, we prepare and characterize CNF supercapacitor electrodes through two different processes, namely, a direct process and a water-transfer process. We elucidate the influence of the production process on the microstructural properties of the CNF, as well as the final electrochemical performance. We show that a change in morphology due to capillary forces doubles the specific capacitance of the wet-transferred CNF electrodes.

使用水转移工艺增强性能的碳纳米泡沫超级电容器电极

碳纳米泡沫（CNF）是一种高度多孔的无定形碳纳米材料，可以通过高通量激光与碳基靶材的相互作用来生产。CNF的形态和电性能使其成为超级电容器应用的理想选择。在本文中，我们通过直接过程和输水过程这两个不同的过程来准备和表征CNF超级电容器电极。我们阐明了生产工艺对CNF的微观结构性能以及最终电化学性能的影响。我们表明，由于毛细管力而导致的形态变化使湿转移的CNF电极的比电容增加了一倍。
