Graphene Oxide Powder

Graphene oxide powder is formed by folding of single graphene oxide. Due to the existence of folding structure, there are micropores and mesopores between graphene oxide sheets, which reduce the stacking between sheets and improve its dispersion and solvent wettability. Traditional graphene powders are prepared by liquid phase exfoliation, oxidation pyrolysis or biomass conversion. They are highly stacked flake graphene materials, which can not give full play to the advantages of single-layer graphene. By controlling the preparation process, the density, specific surface area, oxygen content, defect degree and other parameters of graphene oxide powder can be adjusted to meet the application requirements in different fields.
