摘要:

三维多孔石墨烯作为一种优异的石墨烯碳材料, 其独特的多孔结构使得材料在具有较大比表面积的同时还保持着足够高的电子迁移率和机械稳定性, 在电子器件中得到了广泛的应用. 本文介绍的激光诱导石墨烯是一种以一步法直接制备得到的三维网状石墨烯材料, 该技术将三维石墨烯的制备和图案化相结合, 无需进行湿化学反应处理, 制作方法更简便, 材料性能更优异. 目前研究主要集中在通过掺杂提高性能和利用转移法实现不同基底器件的制备. 激光诱导石墨烯自身特有的属性如多孔微纳米结构和大的比表面积等使其在超级电容器和传感器等领域拥有较高的应用价值.

Abstract:

In recent years, graphene has attracted a lot of interest and research in the fields of chemistry, mechanics and electricity due to its unique properties. As an excellent graphene material, 3D porous graphene has been widely applied in electronic devices due to its unique porous structure, which enables the material to maintain high enough electron mobility and mechanical stability while having a large specific surface area. The laser-induced graphene is a three-dimensional reticular graphene material directly prepared by one-step method. The 3D reticular graphene could be further modified by doping other elements, which can signifi- cantly improve the energy storage capacity of the device. This preparation method combines the preparation and patterning of 3D graphene, eliminates the need for wet chemical reaction treatment, makes it easier to make and has better material properties. At the same time, the special properties of laser-induced graphene, such as porous micro-nano structure and large specific surface area, make it have high application value in the fields of supercapacitors and sensors.

Key words: Three-dimensional reticular graphene, One-step preparation method, Laser-induced graphene, Supercapacitor, Sensor
