The conductivity, long-term stability and temperature behavior of resistors, based on multi-walled carbon nanotube networks embedded in different organic matrixes, has been investigated. A variation of the resistance values over more than 10 orders of magnitude can be achieved by changing the nanotube concentration only by 1 order of magnitude. In particular for epoxy/carbon nanotube compounds an excellent reproducibility of the sample resistance for a constant nanotube concentration, as well as an ideal ohmic behavior and good long-term stability using evaporated gold contacts has been achieved. The application as electrical heating and temperature sensing elements up to temperatures of 160°C has been demonstrated.

Abstract
The conductivity, long-term stability and temperature behavior of resistors, based on multi-walled carbon nanotube networks embedded in different organic matrixes, has been investigated. A variation of the resistance values over more than 10 orders of magnitude can be achieved by changing the nanotube concentration only by 1 order of magnitude. In particular for epoxy/carbon nanotube compounds an excellent reproducibility of the sample resistance for a constant nanotube concentration, as well as an ideal ohmic behavior and good long-term stability using evaporated gold contacts has been achieved. The application as electrical heating and temperature sensing elements up to temperatures of 160°C has been demonstrated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
