As the concentration of carbon black decreases (e.g., in a swollen polymer), the distances between carbon black particles increase, and the resistance of the composite increases gradually. When the concentration of carbon black decreases to a point at which the conductive pathways are disrupted, the resistance of the composite increases sharply (by many orders of magnitude).
Carbon Black o Nerofumo Il nerofumo è una polvere finissima di colore nero composta da residui carboniosi derivanti dalla pirolisi controllata di idrocarburi che può essere utilizzata come additivo per molti materiali. Nelle materie plastiche esso trova impiego come
2006/11/1· Carbon fibers were also added to the polymer-carbon black mixtures to enhance the conductivity and mechanical properties. The electrical conductivity of composites with different ratios of carbon black (CB) content to carbon fiber (CF) content was studied.
One of the more innovative uses for carbon black pigments in the plastics industry is to produce conductive or static dissipative products. Since few plastic resins are inherently conductive, it is necessary to add special fillers to the polymer matrix to give them the desired conductive characteristics.
Polymer grafting of carbon black (CB) has been intensely researched as polymer modifiion is one of the effective means for improving the solubility and compatibility of carbon black. Recent advances in the polymer grafting methods allow the introduction of polymers with well controlled composition, structure and molecular weight onto the surface of CB.
Carbon fiber reinforced polymer (American English), Carbon fibre reinforced polymer (Commonwealth English), or carbon fiber reinforced plastic, or carbon fiber reinforced thermoplastic (CFRP, CRP, CFRTP, also known as carbon fiber, carbon composite, or just carbon), is an extremely strong and light fiber-reinforced plastic which contains carbon fibers.

Carbon black-filled polymer composites have been studied for years due to their ability to conduct electricity when loaded above the percolation threshold. Often times the amount of carbon black required to achieve sufficient conductivity creates difficulties in processing and brittle final composites. In an effort to improve the mechanical behavior of these filled composites without
