Nano carbon black dispersion is discontinuous, highly graphitic, highly compatible with most polymer processing techniques, and can be dispersed in an isotropic or anisotropic mode. They have excellent mechanical properties, high electrical conductivity, and high thermal conductivity, which can be imparted to a wide range of matrices including thermoplastics, thermosets, elastomers, ceramics, and metals. Carbon black dispersion also has a unique surface state, which facilitates functionalization and other surface modification techniques to tailor the nanofiber to the host polymer or application.

Nano carbon black dispersion has attracted much interest in the field of materials, chemistry, and physics due to their unique structures and extraordinary properties. It is generally believed that in carbon black dispersion surface modification is required to dramatically de bundle and homogeneously disperse or dissolve carbon nanofibers in organic solvents or polymers.

Nano carbon black dispersion has been applied as promising materials in many fields, such as energy conversion and storage, reinforcement of composites and self-sensing devices. The carbon nanofibre dispersions and their composites are able to be used in many fields, including sensors, electrode materials, and electromagnetic shielding.

The carbon black dispersion and their composites mainly count on their electrical performances. Carbon black has also been implemented as electrode material for two types of capacitors, namely decoupling capacitors and supercapacitors. As electrode materials, special structural designs and realization to guarantee high specific areas without satisfying mechanical performances is the key factor in enhancing the performances of the current materials.

Nano carbon black dispersion has recently received added attention due to its potential usages in various research and industrial sectors. For instance, the chemical industry, material science, and environmental and energy storage specialties. Preparation of polymer composites carried out through the dispersion of carbon black into the polymer matrices while Carbon black utility in the adsorption of volatile organic compounds (VOC) such as alkanes, aromatics, and chloro-hydrocarbons was also established. Factually, carbon black is a potential material for various engineering applications due to their unique chemical, physical, mechanical, and electrical properties.
