Carbon black particle size is between 10 and 100 nm, while the surface particle size is between 20 and 1,500 m 2 /g. Generally speaking, small carbon black particles with a high surface area are darker, have higher viscosity and lower wettability, are harder to disperse, retain greater conductivity and absorb UV radiation well.

The carbon black conductive agents: acetylene black, 350G, carbon fiber (VGCF), carbon nanotubes (CNTs), Ketjen black (Ketjenblack EC300J, Ketjenblack EC600JD, Carbon ECP, Carbon ECP600JD). [5] Acetylene Black (Polyacetylene): carbon black obtained by continuous pyrolysis of acetylene having a purity of 99% or more obtained by decomposing and ...
Carbon black is a common conductive additive for lithium-ion batteries as the particles have small sizes and a large specific surface areas (SSA) which allow for the additive to be well distributed throughout the cathode or anode in addition to being cheap and long-lasting.
Cabot Corporation Announces New Family of Highly-Conductive Carbon Blacks and Conductive Concentrates for Plastics and Other Applications New products delivering breakthrough conductivity and ...
Conductive Static Dissipative Anti-Static Insulative: Description Carbon powders and fiber: No initial charge. Provides path for charge to bleed off. Typically black color. No or low initial charge. Prevents discharge to or from human contact Initial charges are suppressed. Typically pink color. Insulators and Base Polymers. Not an ESD material
There are two main methods used to synthesize conductive polymers, chemical synthesis and electro (co)polymerization. The chemical synthesis means connecting carbon-carbon bond of monomers by placing the simple monomers under various condition, such as heating, pressing, light exposure and catalyst. The advantage is high yield.
