introduction
Fullerene is a closed cage molecule composed of carbon atoms, which is an allotrope of carbon, and its molecular size is less than 1nm.
about. Due to their unique electronic conjugated structure, fullerenes have excellent optical, electrical and magnetic properties, so they are widely used in biomedicine, new materials and new energy.
Sources and other fields have a wide range of applications. The purity of fullerene is a key indicator affecting its application performance and market value. cosmetics and biomedicine
There is a huge demand for high-purity fullerenes in the pharmaceutical industry. Therefore, formulating the standard for the detection method of fullerene purity can be a great contribution to fullerene scientific research institutes,
Fullerene production enterprises and third-party testing institutions provide unified and standardized testing methods, which will promote the improvement of the quality of fullerene materials and related products.
The rapid development of the industry is of great significance.
