Modeling Carbon-Black/Polymer Composite Sensors - …

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 – Mediapolymer

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
