Expanded graphite is a necessary material for manufacturing flexible graphite. It is made of natural flake graphite through chemical or electrochemical intercalation treatment, washing, drying and high-temperature expansion. Expanded graphite is widely used in the field of environmental protection materials and has played a great role in dealing with many environmental protection aspects. However, there are still some problems and the demand is further improved. Below, the editor takes you to analyze in what ways expanded graphite has been improved as an environmentally friendly material:
1, further improve its hardness, prolong its service life and reduce the preparation cost of expanded graphite;
2. With the help of modern micro-analysis means, the process and mechanism of adsorption of specific substances by expanded graphite are discussed, and the internal relationship between adsorption and analysis process is explained, so as to realize the process control of adsorption of specific substances.
3. Expanded graphite supported photocatalyst, such as titanium dioxide, is an environmental protection material with photocatalytic degradation function and adsorption function, and its function is outstanding. The improvement of the function and response mechanism of composite materials will still be the focus of research.
4. The mechanism and application of expanded graphite in sound absorption data need to be further discussed.
5. Explore the process and mechanism of pollutant removal and transformation in the process of regeneration, and seek green regeneration methods;
6. There is little research on the adsorption function and mechanism of wastewater containing trace oil in the flow state of expanded graphite treatment at home and abroad, which will be an important research direction in the future.
