The existence of these oxygen-containing functional groups greatly changes the original layer structure of graphite.<\/span>\u00a0This increases the layer spacing, and destroys the original electron conjugation system of graphite. Resulting in a significant decrease in its electrical conductivity.<\/p>\nIn terms of magnetism, due to the existence of unpaired electrons in the oxygen-containing functional groups introduced in the oxidation process. These unpaired electrons have a spin magnetic moment, making graphite oxide have a certain paramagnetism.\u00a0When the degree of oxidation is low, the graphite oxide still retains some of the original diamagnetic properties of graphite.<\/span>\u00a0At this time paramagnetism and diamagnetism compete with each other, and the macroscopic magnetic performance is not obvious. However, with the deepening of the degree of oxidation, the paramagnetic signal is gradually enhanced. And when it exceeds a certain threshold, paramagnetism will dominate, making the graphite oxide as a whole show paramagnetism. And its magnetic susceptibility becomes positive.<\/p>\n<\/span>Conclusion<\/span><\/h2>\nGraphite is a diamagnetic substance, and its diamagnetism is generated by the electron induced magnetic moment under the external magnetic field. It is of great significance in a specific scene. Graphite oxide is paramagnetic because it contains unpaired electrons, and the magnetism varies with the degree of oxidation. In-depth research on the magnetism of the two is conducive to improving the theory, promoting innovative applications. And helping the development of new materials and technologies.<\/p>","protected":false},"excerpt":{"rendered":"
In materials science, graphite is a unique carbon material, because of its special structure and properties. It plays a key role in many fields such as writing and industry. However, its magnetism is often ignored and the public’s cognition is vague. The research on the magnetism and nature of graphite is not only related to […]<\/p>","protected":false},"author":3,"featured_media":7297,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-7292","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-carbon-graphite"],"yoast_head":"\n
