Product Description

Product Description

Graphene Oxide Powder

Graphene oxide is the oxide of graphene, generally denoted by GO, the color is brownish-yellow, firstly prepared by the improved Hummers method to get the slurry, and then freeze-dried to get the high-quality graphene oxide powder.GO not only contains SP2 hybridized carbon atoms, part of the carbon-carbon double bond is interrupted by the oxygen-containing functional groups, which becomes the SP3 hybridization; the surface of graphene oxide contains a large number of functional groups, such as -OH, -COOH, -O-, etc. These functional groups give graphene oxide some new properties, such as good dispersion, hydrophilicity, increased interaction with polymers and so on.

 

Product Advantage:

1Using vacuum freeze-drying, higher yield than spray-drying, and the form remains intact;

2Good re-dispersibility, about 30min ultrasonic processing can be restored to the original sol form, to get a stable dispersion

3, Graphene oxide-based materials provide surface modification active sites and large specific surface area;

4, Good dispersion in composite materials, in situ polymerization to prepare multifunctional composite materials, less agglomeration;

5, High purity, less metal impurities;

6Oxidation degree is adjustable and can be customized according to customer's demand;

Frequently Asked Questions

Q: What is graphene oxide?

A: Graphene oxide (GO) is a two-dimensional material in which oxygen-containing functional groups are introduced into the graphene skeleton. The introduction of oxygen-containing functional groups, on the one hand, destroys the ideal π-electron conjugated structure of graphene, changing it from a conductor to an insulator. On the other hand, these functional groups also confer functions such as hydrophilicity, so that graphene oxide can form stable colloids in water and some low molecular weight alcohols. Using these chemically active functional groups, covalent bonding of graphene oxide with other materials can also be realized.

 

 

Q: What types of graphene materials are there?

A: According to the different preparation processes, graphene materials can be divided into two categories: graphene oxide and graphene, and graphene can be divided into graphene microchip prepared by physical method, usually denoted by GNP, and reduced graphene oxide prepared by redox method, usually denoted by rGO, according to the different preparation processes.

 

 

Q: What are the different conditions of use for these three types of graphene products?

A: GO has better hydrophilicity and can be stably dispersed in water without adding any additives, but some lattice defects are introduced in the process of oxidative intercalation, so GO is almost non-conductive; GNP has a complete lattice and better electrical conductivity, but GNP is highly hydrophobic and extremely difficult to be dispersed without dispersing additives and the number of layers is higher than that of graphene oxide; rGO has electrical conductivity and dispersibility between GO and GNP, and the use of rGO is different. The conductivity and dispersibility of rGO is between GO and GNP, and it is necessary to add appropriate amount of dispersing additives in the process of using.
