Description

1-5 layers graphene


Features

1. Lower percolation threshold and more stable conductivity than conductive carbon black, low dosage and high efficiency.

2. Thin film, easy to disperse and process.

3. It is suggested to add about 1-3% in the conductive (electrostatic) coating, which can make the layer excellent conductive (electrostatic) properties, but also have excellent mechanical properties and corrosion resistance;

4. It is suitable for the coating of positive and negative electrode materials of the lithium-ion battery, which can effectively improve the battery energy, cycle life and rate performance.

5. Excellent thermal conductivity, it can be compounded with PA6, PC and other materials to prepare thermal conductivity composite materials.

Applications:

Graphene has a wide range of applications. According to graphene's ultra-thin and super-strength characteristics, graphene can be widely used in various fields, such as ultra-light body armour, ultra-thin and ultra-light aircraft materials. According to its excellent conductivity, it also has great application potential in the field of microelectronics. Graphene may become a substitute for silicon, manufacturing ultra-micro transistors, used to produce future supercomputers; carbon's higher electron mobility can enable future computers to obtain higher speeds. Besides, graphene material is also an excellent modifier. In the field of new energy such as supercapacitors and lithium-ion batteries, due to its high conductivity and high specific surface area, it can be used as an additive for electrode materials.
