Cheapest Factory Price Graphene Nanoplatelets Dispersion Liquid (by Physical Method）

Product Description:

This product is made of natural flake graphite as raw material to get graphene products through physical exfoliation process. It has the advantages of high purity, large specific surface area, high stability, etc. The graphene microfilm exfoliated by physical method does not have the oxidation process of strong oxidizing agent, does not introduce lattice defects, and has excellent electrical conductivity. The most commonly used dispersant is water, while ethanol, ethyl, NMP, DMF, etc. can also be used as a dispersant for graphene. Graphene dispersion is not stable, often need to add an appropriate amount of dispersing additives.

Application fileds:

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.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.

3.Graphene lubricant: Traditional lubricant additives usually contain sulfur, phosphorus, chlorine and other elements, to bring greater harm to the environment, in order to create a green and efficient lubricant products, graphene has become the ideal choice, graphene lubrication and anti-wear performance is very excellent, when the number of layers of 2 ~ 3 layers, its friction is not zero but almost zero. Graphene lubricant can change the friction between the metal rotating parts into sliding between the layers of graphene sheets, and at the same time, it can also fill and repair the uneven pits on the metal surface to meet the dual needs of anti-wear and drag reduction, and prolong the service life of the engine. At the same time, based on graphene's antioxidant and anti-volatility, graphene lubricant can also save fuel and reduce carbon emissions, which is conducive to environmental protection. Currently several categories of graphene materials can achieve the effect of lubrication, but considering the problem of dispersion, the dispersion of graphene oxide is more advantageous.

4.The field of health: Graphene inherent properties determine that it can produce a wavelength of 5 ~ 15μm range of far-infrared radiation energy, and 4 ~ 15μm of far-infrared light is essential for the survival of plants and animals, "the light of life", biological tissues, cells and molecules of the chemical bond vibration, resonance wavelengths are located in most of the 4 ~ 15μm wavelength band. Most of the resonance wavelengths are located in the 4~15μm band when the chemical bonding of biological tissues and cells vibrate, which is basically coincident with the far infrared rays radiated by graphene, thus producing "resonance absorption". Far infrared rays have a strong penetrating ability, not only to the surface of the object, but also can be transported to the object inside the heat, absorbed by the human body can penetrate the skin 3 ~ 5nm, is the temperature of the deep skin rises, to promote blood circulation, and play a role in health care.

Frequently Asked Questions:

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: Is the graphene dispersion sonicated? Does it need to be ultrasonicated again before use?

A: Graphene dispersion is ultrasonically dispersed before leaving the factory, but since the dispersibility of graphene is poorer than that of graphene oxide, it is recommended to ultrasonicate again for 5~10min before use.

Q: What should I do if the dispersion effect deteriorates after storage for a period of time?

A: A small amount of surfactant such as sodium cholate can be added to the dispersion system to reduce the surface tension of graphene and enhance its dispersion effect.

Q: How to store graphene dispersion?

A: It is recommended to keep it in a ventilated, cool and dry environment, and store it separately from strong oxidizers and flammable materials.

Q: What is the particle size of graphene?

A: At present, the particle size of graphene products prepared by chemical method is less than 5μm, and that of graphene products prepared by physical method is 7~12μm, if you need other sizes, please contact us for customization.
