氧化石墨烯纳米剪裁方法

石墨烯纳米剪裁先进方法的研究对于基于石墨烯的电子和光学设备非常重要。本文利用模板法制作反蛋白石结构,并借助反蛋白石纳米网结构,利用光催化还原氧化石墨烯,对氧化石墨烯进行纳米剪裁,形成具有纳米尺度的石墨烯。对还原后的氧化石墨烯表面进行扫描电子显微镜表征和红外光谱表征,并研究剪裁后石墨烯的电学性质。实验表明,反应时间、胶粒大小都会对剪裁后氧化石墨烯的周期和颈宽有影响,进而影响还原后氧化石墨烯的电学性质。利用纳米网状结构对石墨烯进行纳米剪裁是一种可行的方法,通过控制模板尺寸和反应条件可以控制裁剪后的性质。

Nano-cutting Method of Graphene Oxide

Research on advanced methods of graphene nano-trimming is very important for graphene-based electronic and optical devices.In this paper,the inverse opal structure is fabricated by the template method,and the inverse opal nanonet structure is used to perform nano-cutting of graphene by photocatalytic reduction of graphene oxide.Scanning electron microscopy and infrared spectroscopy characterization are applied to study the electrical properties of graphene after cutting.Experiments show that the reaction time and the size of the colloidal particles will affect the period and neck width of the graphene oxide after cutting,thereby affecting the electrical properties of the graphene oxide after reduction.It is a feasible method to use nano-network structure to cut graphene nano-cuts.The properties of the cuts can be controlled by controlling the template size and reaction conditions.
