1. Contains rich oxygen-containing functional groups such as hydroxyl, carboxyl, and epoxy groups, with a thickness of less than three layers;
2. Easy to bond and modify with other functional groups, and through composite with various materials, thus the thermal conductivity, mechanical and other properties of the material can be enhanced;
3. Currently, an annual production capacity of thousands of tons has been achieved.
Chemically Exfoliated Graphene Oxide Powder is a material obtained from flake graphite through chemical oxidation and exfoliation. The material has high purity and degree of exfoliation, while maintaining the planar structure of graphite, with an extremely high aspect ratio (the ratio of particle diameter to thickness). Morion Nanotech uses a self-developed process technic that is more environmentally friendly and results in higher purity, as well as excellent dispersion and stability.
