摘要：

本研究提出并制备了一种以石墨烯森林为电极的摩擦纳米发电机。利用等离子体增强化学气相沉积工艺制备了与其它墙形竖直薄片状的石墨烯形貌差异较大的石墨烯森林。此石墨烯森林具有低薄膜电阻((110±5) Ω/□)以及独特的离散“树状”结构, 有利于石墨烯森林与其他电极材料之间的接触和摩擦。根据石墨烯森林的形貌优势, 将聚酰亚胺膜和石墨烯森林膜作为电极组装摩擦纳米发电机, 其开路电压可达20 V, 短路电流可达0.75 μA。此外, 还讨论了基于石墨烯森林的摩擦纳米发电机的工作原理。最后, 利用此纳米发电机点亮了演示电路中三个不同颜色的LED, 证明了石墨烯森林在摩擦纳米发电机中的有效应用。

Abstract:

This study presents a triboelectric nanogenerator (TENG) with graphene forest as electrode. Graphene forest was fabricated by plasma enhanced chemical vapor deposition (PECVD) process, which shows great different morphology compared with other ‘wall-like’ vertically oriented graphene so far. Graphene forest films are composed of graphene nanoflakes, exhibiting not only low sheet resistance ((110±5) Ω/□) but also uniquely discrete ‘tree-like’ morphology, which are favorable to contact and friction with other materials. According to its morphology superiority, Kapton film and graphene forest film were utilized as electrodes for triboelectric nanogenerator, in which an open circuit voltage of 20 V and a short circuit current of 0.75 μA are obtained. Furthermore, the working principle of the graphene forest based triboelectric nanogenerator was discussed. At last, three LEDs of different color in demo circuit were lighted up by as-prepared nanogenerator, which proves the effective application of graphene forest in triboelectric nanogenerator.

Key words: graphene forest, plasma enhanced chemical vapor deposition, triboelectric nanogenerator
