Graphene is a two-dimensional material formed by a single layer of carbon atoms arranged in a honeycomb pattern, with excellent electrical, thermal and mechanical properties, and is widely used in electronic devices, energy storage, biomedicine and other fields. Traditional graphene preparation methods include chemical vapor deposition and exfoliation, but these methods have disadvantages such as high cost and low yield.
The basic principle of ultrasonic graphene preparation technology is to use the energy of ultrasonic waves to peel off graphene oxide nanosheets dispersed in solution into a single layer of graphene. Under the action of ultrasound, the oxide functional groups on the surface of graphene oxide nanosheets are affected and fractured, resulting in the detachment between graphene layers. At the same time, ultrasound can also accelerate the dispersion of graphene oxide nanosheets in solution and improve the peeling efficiency.
In recent years, important progress has been made in the preparation technology of ultrasonic graphene. The researchers improved the peeling efficiency and graphene yield by optimizing parameters such as ultrasonic power density, solution concentration, and temperature. At the same time, they also explored different ultrasonic-assisted methods, such as microwave-assisted and electrochemical-assisted, to further improve the effect of ultrasonic graphene preparation technology. In addition, the researchers also studied the industrial application prospect of ultrasonic graphene preparation technology, which provides strong support for the practical application of this technology.
As a green and efficient synthesis method, ultrasonic graphene preparation technology has a wide range of application prospects. First of all, this technology can be applied to the field of electronic devices, such as graphene field-effect transistors, graphene solar cells, etc., to improve the performance and stability of devices. Secondly, ultrasonic graphene preparation technology can be applied to the field of energy storage, such as graphene supercapacitors, graphene batteries, etc., to improve the efficiency and safety of energy storage. In addition, this technology can also be applied to biomedical fields, such as drug delivery, bioimaging, etc., providing new tools and methods for biomedical research.
As a new type of green synthesis method, ultrasonic graphene preparation technology has the advantages of high efficiency and environmental protection. The research progress and application prospects of this technology show that it will play an important role in promoting the development of graphene-related fields in the future. With the continuous progress and improvement of technology, it is believed that the preparation technology of ultrasonic graphene will be applied and promoted in more fields.
