Flooring, conducting/antistatic

Blacks used to produce conductive and antistatic plastics are chiefly high-structure furnace blacks with relatively fine particles and low contents of volatile constituents. Black concentrations are around 10-40% for conductive systems. Antistatic plastics (e.g., cable sheathing and floor coverings) contain 4-15% carbon black.

For specialised applications where electrical conductivity is required, such as antistatic flooring or shielding of electromagnetic induction, specific carbon black pigment/filler is used. Copper and nickel metal powders have also been studied (112). A review is available of the electrical properties of polymers filled with different types of conducting particles (416).

Conductive blacks are used in high-voltage cables, electronic packaging, antistatic flooring, EM shielding, fuel injectors and tanks, and computer assembly stations. Carbon black can be used in polyethylene and its copolymers to produce positive temperature coefficient (PTC) materials for use in thermistors and other electrical devices. 

Sensitive explosive azides can be also easily ignited by electrostatic discharge (ESD). Therefore, wear ESD protective clothing (or at least cotton clothes) and antistatic shoes. The laboratory floor should be ESD conductive or there should be at least static dissipative mats (ESD mats) installed in front of the fume hood where the azides will be synthesized and handled. 

External antistatic additives are mostly used for fibers, e.g., PVC floor finishing. Usually the article is sprayed with a solution containing the additive. It is important to emphasize that 3,4-poly(ethyl-enedioxythiophene) belongs to the class of conductive coatings (10).
