Factory price single layer graphene oxide powder/nano graphene powder
Graphene is an isoform (form) in which a single layer of carbon atoms is arranged in a hexagonal lattice. It is the basic structural element of many other isomorphs of carbon, such as graphite, diamonds, carbon, carbon nanotubes and fullerenes.
Graphene differs from conventional 3D materials in that it is a semi-metal or zero-gap semiconductor. It has a remarkable electron mobility at room temperature and it has been showed it.
is a new type of internal heating material. Graphene internal heating fiber is a kind of intelligent multifunctional fiber material which is made up of biomass graphene and various kinds of fibers. It has low temperature and far infrared function and is antibacterial and antibacterial. Anti-UV, anti-static and so on. The fabric material made of biomass graphene has no difference in touch and common fabric, but has unique effects on functions such as internal warming, bacteriostatic, ultraviolet protection and deodorization. It can even function as a warming palace and relieve cervical pain. Since the electrothermal conversion efficiency of graphene can reach 99%, it has an absolute advantage compared with other heat-generating materials. Secondly, the traditional resistance wire heats up, and it is prone to short-circuit fire, water-uninterrupted power, and human comfort.
The conductive ink is an ink made of a conductive material and has a certain degree of conductivity, and can be used as a printed conductive point or a conductive line. In recent years, it has become more and more widely used in industries such as mobile phones, toys, membrane switches, solar cells, far-infrared heating films and radio frequency identification technologies. In the past few decades, the largest downstream of conductive inks has been solar cells and display devices. Future applications including touch sensors and their electrodes, RFID and electronic paper will also continue to grow.
Graphene has a wide range of applications in sensors due to its unique two-dimensional structure. It has the characteristics of small volume, large surface area, high sensitivity, fast response time, fast electron transfer, easy to fix proteins and maintain its activity. Item performance. Mainly used in the production of gas, bio-small molecules, enzymes and DNA electrochemical sensors. Nanyang Technological University in Singapore has developed a graphene light sensor with a sensitivity of 1000 times that of a conventional sensor; Rensselaer Polytechnic Institute of the United States has developed an inexpensive graphene sponge sensor that far exceeds the existing commercial gas sensor.
Graphene materials have many applications in the biological field. Among them, graphene oxide can be made into nano-antibacterial materials, and its antibacterial property stems from its destruction of E. coli cell membrane. Due to its rich material sources, this new crystal material is expected to be widely used in environmental detection and clinical medicine.
4.Energy storage materials
Graphene also plays an important role in energy storage. Hydrogen has always been regarded as a very high-quality energy source. However, due to its low density and explosive nature, hydrogen storage materials have always been a hot spot for research. Graphene The emergence of class materials will be widely used in hydrogen energy storage.
Graphene is widely used in lithium ion batteries. It has been commercialized as a conductive additive in cathode materials to improve the conductivity of electrode materials and improve rate performance and cycle life. Currently, a more mature application is to use graphene as a conductive paste to coat a positive grade material such as iron phosphate. At present, the coating slurry for a positive electrode mainly includes a graphite slurry, a carbon nanotube slurry, etc., and with the mass production of graphene powder and graphene microchip powder, graphene paste is displayed more and the cost is continuously lowered. Good coating performance. As lithium batteries grow, graphene pastes will increase steadily. Lithium-ion batteries are mainly used in mobile electronic devices, such as mobile phones, notebook computers and video cameras, and are actively expanding into new energy vehicles such as electric vehicles, and have long-term development prospects.
Graphene is considered to be an ideal material for replacing silicon, and a large number of powerful companies have developed graphene semiconductor devices. Sungkyunkwan University in Korea has developed a high-stability n-type graphene semiconductor that can be used in the air for a long time. Columbia University has developed a graphene-silicon optoelectronic hybrid chip, which has broad application prospects in the field of optical interconnects and low-power photonic integrated circuits. IBM researchers have developed graphene field-effect transistors with cut-off frequencies up to 100 GHz and frequency performance well above the cutoff frequency (40 GHz) of the most advanced silicon transistors of the same gate length.
