Overview of Graphene powder

Graphene is a two-dimensional material composed of carbon atoms that are bonded in sp² hybridized orbitals to form a hexagonal honeycomb lattice structure. It is a single layer of carbon atoms exfoliated from a graphite material. It is only 0.335 nanometers thick, equivalent to approximately one-half millionth of the diameter of a hair, making it one of the thinnest and hardest materials known.

Characteristics of Graphene powder

1. High strength: Graphene has extremely high tensile strength, one of the strongest of any known material.
2. High electrical conductivity: the movement of electrons in graphene is virtually unchecked, exhibiting extremely high electrical conductivity, close to that of metals but at the same time transparent.
3. High Thermal Conductivity: Its thermal conductivity is very high, far exceeding that of many common thermal conductive materials such as copper.
4. High Transparency: Extremely high transparency to visible light, suitable for applications such as transparent conductive films.
5. Large specific surface area: the monolayer structure gives graphene a great specific surface area, which is favorable for adsorption, catalysis, and other applications.
6. Highly tunable: the properties of graphene can be adjusted by chemical or physical methods to meet the needs of different applications.

Application of Graphene 

Electronic devices: Due to their excellent electrical properties, graphene has been investigated for the manufacture of ultra-fast transistors, transparent conductive films, flexible displays, and so on.
Energy storage and conversion: Graphene as an electrode material can enhance the energy density and charging speed of batteries (e.g., lithium-ion batteries) and is also used in solar cells and supercapacitors.
Composite materials: added to plastics, rubber, and resin can enhance the mechanical properties of the material, used to make lighter and stronger composite materials, applicable to aerospace, automobile manufacturing, and other fields.
Sensors and detectors: Graphene’s high sensitivity makes it an ideal material for making all kinds of sensors, including gas sensors and biosensors.
Biomedicine: Used in drug delivery systems, tissue engineering, bio-imaging, etc., due to its good biocompatibility and adjustability.
Environmental protection: water purification, air filtration, and pollutant adsorption using its large surface area.

FAQ
Q1
What is graphene?
Answer: Graphene has excellent optical, electrical, and mechanical properties. It has the potential to revolutionize applications in many fields, such as materials science, micro and nano processing, energy, biomedicine, and drug delivery.
Q2
What is graphene used for?
Answer: Graphene has a wide range of potentially revolutionary applications in a number of fields. For example, the electronics industry, battery technology, solar cells, reinforcement materials, biosensors, drug delivery, environmental protection, transparent electrodes, catalyst carriers, protective materials, aerospace, desalination, energy storage materials, smart textiles, wireless charging technology, and other fields.
Q3
What is graphene made of?
Answer: Graphene is made of carbon atoms, as a two-dimensional material made of a single layer of carbon atoms closely arranged; this single layer of carbon structure gives graphene extremely excellent physical and chemical properties, such as high strength, high electrical conductivity, high thermal stability, and almost complete transparency.
Q4
What is graphene oxide?
Answer: Graphene Oxide (GO) is a graphene-based material that is produced by chemically oxidizing graphene. In this process, the carbon skeleton of graphene will introduce a large number of oxygen-containing functional groups, such as hydroxyl, epoxy, carboxyl, and carbonyl groups. These oxygen-containing groups significantly change the original properties of graphene, making it more chemically active and hydrophilic than pure graphene, and can be well dispersed in water and polar solvents to form stable solutions or sols.
Q5
What is graphene oxide used for?
Answer: Graphene oxide has a wide range of potential applications due to its rich surface functional groups and amphiphilicity in materials science, biomedicine, environmental science, energy storage, and other fields, such as the preparation of composite materials, sensors, drug delivery systems, filtration membranes, electromagnetic shielding materials and so on.
Q6
Is graphene stronger than diamond?
Answer: Graphene is the strongest material ever recorded, more than 300 times stronger than A36 structural steel at 130 gigapascals and more than 40 times stronger than diamond.
