Nanocomposite NTC resistor type temperature sensors have been realized by mixing a high concentration of multi-walled carbon nanotubes with Syndiotactic Polystyrene. The initially slightly unstable electrical characteristics have been stabilized by applying gradually higher voltages but limiting the maximum current. After this short burn-in procedure, linear and stable current-voltage and temperature-current characteristics have been obtained and the value of the temperature coefficient could be notably increased.

Abstract
Nanocomposite NTC resistor type temperature sensors have been realized by mixing a high concentration of multi-walled carbon nanotubes with Syndiotactic Polystyrene. The initially slightly unstable electrical characteristics have been stabilized by applying gradually higher voltages but limiting the maximum current. After this short burn-in procedure, linear and stable current-voltage and temperature-current characteristics have been obtained and the value of the temperature coefficient could be notably increased.File in questo prodotto:
