Product Description
Product Description:
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 Advantages:
1, Graphene oxide-based materials provide surface modification active position and large specific surface area;
2, Good dispersion in composite materials, in situ polymerization to prepare multifunctional composite materials with less agglomeration;
3, High purity, less metal impurities;
4, Adjustable oxidation degree, can be customized according to customer needs;

Application fields:
1, Textile field: Graphene materials and ordinary textiles’ effective combination, can make the textile retain their own performance ,meanwhile access to graphene’ one or several special properties, such as conductive, flame-retardant, antibacterial, anti-ultraviolet ray, anti-electromagnetic radiation, magnetic therapy, anionic health care, etc., can be applied in the field of special protection, smart fabrics and so on;
2, Graphene photocatalytic materials: Graphene/titanium dioxide photocatalytic materials in the visible light or ultraviolet light has a strong reducing ability, stable chemical properties, can be formaldehyde, toluene, xylene, ammonia, odor, bacteria, microorganisms, and other harmful organic matter completely decomposed into carbon dioxide and water. Graphene/titanium dioxide photocatalytic material can be applied to various photocatalytic sprays for air pollution treatment, such as applied to indoor air purification, formaldehyde removal, outdoor environment air purification, etc.; nano antimicrobial coatings; wastewater treatment, such as decomposition of organic matter in wastewater from paper mills, dyeing and printing factories, and chemical plants. The application prospect is broad.
3.Construction materials: Graphene construction materials are formed by using graphene as the core and compositing with other materials through its high strength and strain hardening properties. The characteristics of graphene flakes can be utilized to strengthen the thermal conductivity and strength of the material, while effectively reducing the density of the material. Usually in the concrete material to increase a strength level, a single square of concrete need to increase 30kg cement, if mixed with graphene, then to achieve the same strength level, can save cement about 10%. The advantages are high strength, good thermal conductivity, good emissivity and oxidation resistance.In 2018, a hospital in London, UK, applied a roof built with graphene material. This roof utilizes special 3D printing and steel structure, and through the high thermal conductivity of graphene material, the temperature inside the hospital will be drastically reduced in the summer, saving the hospital's air conditioning energy consumption.
4.Graphene anti-corrosion coatings: Graphene material in the sheet diameter is very small can still maintain a great diameter-thickness ratio, add a small amount of graphene in the coating on the line to effectively form a lap, the formation of a more complete shielding layer, delay the penetration of corrosive media, greatly reducing the permeability of chloride ions. Some practical applications show that when the amount of GO added is 0.5%, the chloride ion permeability of the coating can be reduced by 50%. On the other hand, the use of graphene's high conductivity, add a very small amount of zinc powder coating (<0.3%), the coating and zinc powder can form a conductive network, improve the utilization of zinc powder, so that the entire coating relative to the steel to become the "anode", and significantly improve the cathodic protection performance of the zinc powder primer.
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 are the categories of graphene materials?
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 nanosheets 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: Can graphene oxide dispersion be used directly?
A: It can be used directly after opening, if it has been placed for a long time, it can be used after ultrasonic dispersion for 5~10min, the ultrasonic time should not be too long, after the ultrasonic time is too long, the temperature of the water bath rises, and graphene oxide is easy to deoxidize, resulting in poor dispersion effect.
Q: Graphene oxide can be dispersed into which agents?
A: Graphene oxide can be stably dispersed in water due to a large number of oxygen-containing functional groups, in addition, ethanol, acetic acid, NMP, DMF and so on are also good dispersants of graphene oxide.
Q: How to store the unused graphene oxide dispersion after opening?
A: It is recommended to be stored in a ventilated and dry environment at a temperature not higher than 35℃, do not contact with metals, vitamin C, NaHSO3, NaBH4 and other reducing reagents when storing, and keep it sealed at low temperature after opening.
Q: What is the particle size of graphene oxide?
A: At present, the particle size of our graphene oxide products is less than 5μm, if you need other sizes, please contact us for customization.
Q: Is the smaller the particle size of graphene oxide, the better the dispersibility?
A: The dispersibility of graphene oxide has a little relationship with the particle size, but there is no direct influence on the relationship, the more critical influencing factor is the degree of oxidation as well as the dispersing technology, the oxygen content of more than 20% of the GO has been able to meet the normal dispersion needs.
