Single Layer Graphene Oxide Powder

Single Layer Graphene Oxide Powder

Introduction:

Single-layer graphene oxide powder refers to a powdered form of graphene oxide consisting of individual graphene oxide sheets, with each sheet being only one atom thick.

Chemical oxidation processes produce graphene oxide from graphite, resulting in the insertion of various oxygen-containing functional groups onto the graphene basal planes and edges.

The “single-layer” aspect indicates that each graphene oxide sheet in the powder consists of a single layer of carbon atoms, similar to pristine graphene, but with the addition of oxygen functional groups. These functional groups, such as epoxides, hydroxyls, and carboxyls, introduce defects and disrupt the sp² hybridization of carbon atoms, rendering graphene oxide an insulator with reduced electrical conductivity compared to pristine graphene.

It retains many of the unique properties of graphene, such as high surface area, mechanical strength, and chemical versatility, while also exhibiting properties specific to graphene oxide, such as hydrophilicity and dispersibility in water.
