What are the important indicators for evaluating the conductive performance of conductive carbon black?

Before introducing the background and application fields of conductive carbon black, let us first understand the factors that affect its conductive properties.

 

 

Factors affecting the conductivity of conductive carbon black

Particle size and specific surface area: The conductive performance of conductive carbon black is closely related to its particle size and specific surface area. Smaller particle size and larger specific surface area can provide more conductive paths and contact points, thereby increasing conductive properties.

 

Structure and morphology: The structure and morphology of conductive carbon black also affect its conductive properties. The highly crystalline morphology and shorter chain structure contribute to improved conductivity.

 

Dopants: By introducing dopants, such as metals or other substances with good conductive properties, into conductive carbon black, its conductive properties can be significantly improved.

Printing inks: Conductive carbon black can be used in the preparation of printing inks, providing excellent conductivity and durability. This kind of conductive ink is often used to make conductive films, conductive papers, conductive printed circuit boards, etc.

 

Electronic products: Conductive carbon black plays an important role in electronic products. It can be used to prepare conductive films, conductive glues and conductive adhesives to provide reliable electrical connections and conductive properties.

 

Energy storage: Conductive carbon black is also widely used in energy storage areas, such as lithium-ion batteries and supercapacitors. In these applications, conductive carbon black can increase the conductivity and charge transfer speed of electrodes and improve energy storage efficiency.

 

 

Indicators of good electrical conductivity of conductive carbon black

The conductive performance of conductive carbon black can be evaluated by the following indicators:

 

Resistivity: The lower the resistivity of conductive carbon black, the better its conductivity.

 

Conductivity: The conductivity of conductive carbon black is another important indicator of its conductive properties. Higher conductivity indicates better electrical conductivity.
