Embodiment 1

[0026] Prepare a kind of reduced graphene oxide paper, the method is as follows:

[0027] Step 1: Irradiate a 532nm wavelength laser emitted by a 60mW laser onto a certain point on the graphene oxide paper for 1-2 seconds.

[0028] Step 2: Put the graphene oxide paper after laser irradiation into a microwave oven (1000W, 2450MHz), irradiate with microwave for 3 seconds, observe the luminescent phenomenon once, stop the microwave irradiation, and obtain reduced graphene oxide paper.

[0029] The Raman spectrum of the graphene oxide paper after laser irradiation obtained in step 1 is as follows: figure 1 Shown in curve 2 in, the Raman spectrum of the reduced graphene oxide paper that step 2 obtains is as follows figure 1 Shown in curve 1. Depend on figure 1 It can be seen that it is still graphene oxide after laser irradiation; but after the microwave irradiation in step 2, the D peak of the curve becomes weaker and a 2D peak appears, which fully shows that the graphene oxide...

Abstract

The invention discloses a preparation method of reduced graphene oxide paper. The preparation method comprises the following steps: step 1, irradiating graphene oxide paper for 1-2 seconds by using a laser point; and step 2, putting the graphene oxide paper obtained in the step 1 into a microwave oven for microwave radiation, and stopping microwave radiation when 1-2 times of luminescence occurs. The invention also provides the reduced graphene oxide paper prepared by the method. According to the preparation method of the reduced graphene oxide paper, the graphene oxide paper is irradiated by the laser point, so that the graphene oxide paper is triggered at the irradiation point and responds to microwaves, and the reduced graphene oxide paper with conductivity can be obtained through reduction by using microwaves without damaging the integrity of the graphene paper. The method disclosed by the invention is simple and easy to operate and low in cost, can be completed under the conditions of air and room temperature, does not need complicated and expensive equipment, and is suitable for large-scale preparation of high-quality graphene paper.

Description

technical field [0001] The invention belongs to the field of graphene paper preparation, in particular to a reduced graphene oxide paper and a preparation method thereof. Background technique [0002] Graphene is composed of a single layer of carbon atoms, has excellent physical, chemical and structural properties, and has important applications in the fields of semiconductors, energy, composite materials and sensing. Reducing graphene oxide can significantly improve performance, and reduced graphene oxide (RGO), even in a disordered form, has been shown to be a potential candidate in energy storage, conductive inks, sensing, ion sieving, composite materials, etc. Useful material. The preparation methods of reduced graphene oxide can be mainly divided into thermal reduction method and chemical reduction method, but these methods often involve high energy consumption or potentially dangerous chemical reducing agents. [0003] In recent years, many non-chemical reduction met...
