The Importance of Conductive Fiber

The Importance of Conductive Fiber

Generally, fibers with a resistivity of less than 107 (Ω·cm) are defined as conductive fibers. Fibers spun by mixing conductive media in polymers, such as chemical fibers, metal fibers, and carbon fibers, can be classified as conductive fibers. This type of fiber has good electrical conductivity and durability, especially good durability and antistatic properties under low humidity, making it a great material to be used in industrial, civil and other fields.

Accelerate Research and Practice of Graphene in Conductive Fiber

There are generally two methods for preparing conductive fibers. One is to coat the surface of conventional fibers with conductive components, and the other is to mix and spin conductive materials with fiber raw materials. The conductive fiber prepared by the coating method has outstanding conductivity, but it has poor washing resistance and durability. Graphene has excellent electrical conductivity because its electrons can move freely through the graphene crystal at a speed much faster than that of ordinary conductors. The graphene material is compounded into existing fibers by in-situ polymerization, melt spinning or wet spinning. An effective circuit is formed by stacking graphene on the body phase or surface of the fiber. The made graphene conductive fiber can generate a large current under the condition of a lower voltage load, which gives the fiber material more functions.

The main technical route of Alfa Chemistry is as follows: based on the chemical properties of the fiber material itself and the ability to bind to graphene, in conjunction with the existing preparation technology and characteristics of graphene, the graphene is firmly supported on the surface. Alfa Chemistry currently has produced various graphene conductive fibers. At the same time, we also provide corresponding preparation technology and a full set of production line construction and guidance.

What Can We Do?

  1. We provide a complete graphene production line design to provide raw materials for the use of conductive fiber materials.
  2. We design the corresponding electrical conductivity according to the customer's specific fiber performance requirements.
  3. We can customize solutions to improve the use of graphene in conductive fibers according to our customers' needs.
