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.

Carbon black (with subtypes acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking in a limited supply of air.
Conductive agents are used to ensure electrodes have good charge and discharge performance. Usually, a certain amount of conductive material is added during the production of the pole piece, and the micro current is collected between the active material and the current collector to reduce the micro current.
The thermal conductivity of a material is a measure of its ability to conduct heat.It is commonly denoted by , , or and is measured in W·m −1 ·K −1.. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity.
A thermal interface material (shortened to TIM) is any material that is inserted between two components in order to enhance the thermal coupling between them [1].A common use is heat dissipation, in which the TIM is inserted between a heat-producing device (e.g. an integrated circuit) and a heat-dissipating device (e.g. a heat sink).
These applications utilize permanent antistatic agents or conductive additives such as carbon black, conductive fibers, and nanomaterials. [3] [4] An antistatic agent for the treatment for coatings may also involve an ionic liquid or a solution of a salt in an ionic liquid. [5] Indium tin oxide can be used as transparent antistatic coating of ...
With the support of his wife, Linda Datcher Loury (herself a highly regarded economist), Alcoholics Anonymous (A.A.), and colleagues, Loury managed to rise above it and not just rebuild his ...
Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher the resistivity). Conductivity measurements in water are often reported as specific conductance, relative to the conductivity of pure water at 25 °C.
