What is Graphene?
Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms in a hexagonal honeycomb lattice with special hybrid orbitals. It has excellent optical, electrical, and mechanical properties. Materials with light weight, strongest toughness, best light transmittance, and best electrical and thermal conductivity have important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery.
Applications of Graphene in Nanotechnology
Graphene has become a research hotspot in the fields of new materials, energy, electronics, medicine and environmental protection due to its unique two-dimensional honeycomb carbon nanocrystal structure and excellent photoelectric and thermal properties.
Graphene in Electronics
Graphene is a transparent and good conductor material, suitable for the production of light panels, touch screens, solar cells, sensors, transistors and other products, as well as for ultra-light aircraft materials and aerospace military fields.
Graphene in Energy Storage
Due to its low mass, high stability, and substantial specific surface area, graphene has become a research focus for new energy batteries. A flexible photovoltaic panel with a graphene nano-coating on the surface has been successfully created by the Massachusetts Institute of Technology. This innovation can significantly lower the price of producing transparent and deformable solar cells. Small digital devices like cameras and night vision goggles may use this battery. an internal device application.
Graphene in Biomedical Applications
Graphene oxide is an excellent material for creating biosensors because of its large specific surface area, small thickness, and numerous functional groups on the surface. In addition, due to its unique optical characteristics, graphene oxide is frequently used in clinical medical imaging and other fields. For the purpose of achieving drug delivery in vivo, graphene oxide’s hydrophilicity, flexibility, biocompatibility, and conductivity make it possible to load a significant quantity of water-insoluble drugs.
Graphene in Environmental Protection
Graphene can be used as a new type of adsorbent material due to its layer floc structure, excellent characteristics and functional modification, and has great application potential in the remediation of heavy metal pollution in environmental water and soil, and air pollution control. Studies have shown that graphene has a good adsorption effect on heavy metals such as lead and cadmium in soil, organic matter such as organic dyes, antibiotics, and oil in sewage, and antibiotics, dust and harmful gases in the atmosphere.
Types of Graphene provided by Matexcel
Carbon Nanotubes
Carbon nanotubes can be regarded as curled graphene sheets, so according to the number of layers of graphene sheets, they can be divided into single-walled carbon nanotubes and multi-walled carbon nanotubes. According to their structural characteristics, carbon nanotubes can be divided into several types such as armchair nanotubes and zigzag nanotubes.
Graphene Aerogel is a kind of high-strength oxidized aerogel, which has the characteristics of high elasticity and strong adsorption, and has broad application prospects.
Graphene Coatings
Graphene can be used in coatings to prepare pure graphene coatings and graphene composite coatings. The former mainly refers to functional coatings in which pure graphene plays the role of anti-corrosion and electrical conductivity on metal surfaces; Graphene can significantly improve the performance of the resin, so graphene composite coatings have become an important application research field of graphene.
Graphene Nanopowder
The product has excellent dispersion properties in various polar solvents and polymer matrix materials, and can be widely used in many fields such as new energy, new materials, construction, electronic information, aerospace and national defense.
Graphene sheets are also known as graphite heat sinks, high thermal conductivity graphite films, and synthetic graphite. They have a graphene structure and have excellent heat transfer and sub-homogeneous capabilities in the horizontal direction, which can make heat disperse more evenly.
Other types of graphene products are also available at Matexcel, including fullerene, functionalized graphene, functionalized graphene oxide, graphene composite, graphene dispersion/slurry, reduced graphene oxide, etc.
