Areas of application:
1.Graphene-based battery: Using graphene as a lithium-ion battery conductive agent can build a conductive network that is "soft, thin and dense", greatly reducing the amount of conductive agent, significantly improving the volume energy density and charge and discharge performance of the battery, which means that more energy can be stored in the same space, improving the endurance of mobile phones and electric vehicles.
2.Textile field: Graphene materials and ordinary textiles’s effective combination, can make the textile retain their own performance ,meanwhile access to graphene’s 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;
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.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 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 nanoplatelets prepared by physical method, usually denoted by GNP, and reduced graphene oxide prepared by chemical reduction process, usually denoted by rGO, according to the different preparation processes.
Q:How to disperse the graphene powder?
A:Through simple ultrasonic treatment, the graphene powder can be dispersed in agents such as water, ethanol, acetic acid, DMF, NMP, etc
Q:How to do if graphene powder dispersion effect is not so good?
A:A small amount of sodium cholate surfactant can be added to the dispersion system to reduce the surface tension of graphene and enhance its dispersion effect
Q:How to store graphene powder?
A: It is recommended to keep it in ventilated, cool and dry environment, and store it separately from strong oxidizers and flammable materials. Long time storage will lead to powder absorb moisture easily, which can be dried in low temperature before use.
Q: What is the particle size of graphene?
A: At present, the particle size of our rGO with chemical reduction process is less than 5μm, the physical method produced graphene nanoplatelet is 7~12μm , please contact us for customization if you need other size.
