Description
Graphene Oxide Water Dispersion, Purity: 99.5%, Black Liquid, GO: 2.0 wt%
Graphene oxide (GO) is an oxidized derivative of graphene, featuring a highly functionalized structure and distinctive characteristics. Due to the negative surface charge introduced by oxygen-containing groups, GO disperses effectively in polar solvents like water without the need for surfactants. In its aqueous dispersion form, GO appears as a black, odorless liquid comprising mainly single-layer and few-layer flakes.
One of GO’s standout features is its surface chemistry. The covalent and non-covalent functionalization provided by hydroxyl, epoxide, and carboxyl groups enables strong interactions with a wide range of chemical species. These include hydrogen bonding, van der Waals forces, and ionic interactions. This makes GO especially suitable for integration into polymer, ceramic, and composite matrices, significantly enhancing their thermal, mechanical, and chemical properties.
Although GO is an electrical insulator by nature, it serves as a precursor to reduced graphene oxide (rGO), which partially restores the graphene lattice and imparts moderate conductivity. The oxygen functional groups in GO contribute to its hydrophilicity, allowing for long-term dispersion stability in water without settling or agglomeration.
Applications
- Transparent conductive films
- Solar energy storage systems
