Carboxylated graphene oxide dispersionDiameter>500nm

Overview
Carboxyl Graphene Oxide Dispersion is an aqueous suspension of functionalized graphene oxide flakes with controlled dimensions exceeding 500 nm. This specialized nanomaterial builds upon the fundamental properties of graphene oxide—first synthesized in 1859 by Benjamin Brodie—while offering enhanced electrical conductivity and mechanical strength due to its larger flake size. The material consists of atomically thin carbon layers featuring sp²/sp³ hybridization and oxygen-containing functional groups including carboxyl, hydroxyl, and epoxy groups. Produced via optimized oxidation methods such as the Hummers process, this dispersion is particularly suitable for applications requiring superior electrical percolation, mechanical reinforcement, and large-area coating capabilities.
