Graphene is a new black technology fabric that may change the future
Graphene is a high-tech nanomaterial, which is obtained after being stripped from graphite. It is more expensive than gold and is called “black gold”.
Graphene exists in graphite in nature. Although graphite is common, graphene is particularly difficult to peel off. Two physicists from the University of Manchester (Andre Geim and Konstantin Novoselov) successfully separated graphene from graphite and jointly won the 2010 Nobel Prize in Physics.
Modern applications of graphene
With the gradual breakthroughs in mass production and large size problems, the pace of industrial application of graphene is accelerating. Based on existing research results, commercial applications will be realized first. It may be in the fields of mobile devices, aerospace, and new energy batteries.
Sensor
Graphene can be made into chemical sensors. This process is mainly completed through the surface adsorption properties of graphene. According to the research of some scholars, the sensitivity of graphene chemical detectors can be compared with single molecule detection. Comparable to the limit. Graphene’s unique two-dimensional structure makes it particularly sensitive to its surrounding environment. Graphene is an ideal material for electrochemical biosensors. Sensors made of graphene have good sensitivity in medical detection of dopamine, glucose, etc.
Desalination
Graphene filters are used more than other desalination technologies. After the graphene oxide film in a water environment comes into intimate contact with water, it can form a channel about 0.9 nanometers wide, and ions or molecules smaller than this size can quickly pass through. By further compressing the capillary channel size in the graphene film through mechanical means and manipulating the pore size, salt in seawater can be efficiently filtered.
Aerospace
Due to its high conductivity, high strength, ultra-thinness and other characteristics, graphene has outstanding application advantages in the aerospace and military fields. In 2014, NASA developed a graphene sensor for use in the aerospace field, which can detect trace elements in the Earth’s high-altitude atmosphere and structural defects on spacecraft. Graphene will also play a more important role in potential applications such as ultra-light aircraft materials.
Biology
Graphene is used to accelerate the osteogenic differentiation of human bone marrow mesenchymal stem cells, and is also used to create biosensors with epitaxial graphene on silicon carbide. At the same time, graphene can serve as a neural interface electrode without changing or damaging properties, such as signal strength or scar tissue formation. Due to properties such as flexibility, biocompatibility and electrical conductivity, graphene electrodes are much more stable in the body than tungsten or silicon electrodes. Graphene oxide is very effective in inhibiting the growth of E. coli without damaging human cells.
Graphene technology
Graphene is a sheet composed of a single layer of carbon atoms It is a new material with a thin, hard, thermally conductive and electrically conductive nanomaterial known in the world. Applied to the field of fabrics, it can improve human microcirculation, enhance human immunity, take away human metabolites, and reduce the probability of major diseases.
Many traditional heating materials (such as carbon fiber) have poor flexibility and are prone to breakage when bent. Graphene exists in the form of fabric. It is not only soft in texture, but also washable. It does not break even when twisted and knotted, making it safer and more durable. Just by turning on electricity, it can quickly generate heat (convert electrical energy into thermal energy) and produce far-infrared waves that are beneficial to the human body.
Exploring Graphene Fiber → Fabric
Graphene is the thinnest and strongest fiber yet discovered , a new type of nanomaterial with strong electrical and thermal conductivity, known as “black gold” and “king of new materials”. Graphene fiber is made from biomass graphene and natural fiber blended chemical fiber fabrics. The fabric made of this fiber is as thin as a cicada’s wing, strong and durable, dustproof and water-proof, warm and breathable, permanently eliminates static electricity, and has strong anti-static properties. Bacteria and mite removal function. The GA-T24253 test found that graphene fiber fabric has an efficient blocking effect on pneumonia, Escherichia coli, Staphylococcus aureus, and Candida albicans.
The resistivity of graphene is very small, so it has The particularly excellent electrical conductivity is also the main reason why graphene is antistatic. In addition to being antistatic, graphene also has electromagnetic shielding functions. These functions also make graphene fabrics the preferred fabric for protective clothing.
StoneGraphene fabric has extremely strong stretch and strength, and the fabric also has particularly good elasticity. Graphene fabric also has good antibacterial properties. The fabric itself is non-toxic and is skin-friendly and comfortable after being made into clothing. Especially excellent wearing experience. At the same time, it can also be worn close to the body. The graphene fabric has good protection and health care effects.
Graphene protective clothing can not only be washed and used repeatedly, but also can release far-infrared to increase one’s own immunity, block virus intrusion, and is also permanently dust-free and static-free.
Therefore, the advantage of graphene fabric is to strengthen the function of skin immune cells,
It can be stimulated by body temperature Far infrared waves, antibacterial and antibacterial.
It is a natural filter for the body and the outside world, combined with its powerful far-infrared function.
It is a new breakthrough in the clothing revolution in the new era. It breaks the traditional material manufacturing process.
