A low density polyethylene based nanocomposite sample with a high concentration of multiwalled carbon nanotubes has been shown to have a rather high value of the electrical resistance temperature coefficient with a PTC type behavior over the whole investigated range between room temperature and 70°C. Due to a long-term drift of the electrical characteristics this type of nanocomposite cannot be used as stable temperature sensor but, after an initial burn-in procedure, a reliable operation as current limiting element has been demonstrated.

Abstract
A low density polyethylene based nanocomposite sample with a high concentration of multiwalled carbon nanotubes has been shown to have a rather high value of the electrical resistance temperature coefficient with a PTC type behavior over the whole investigated range between room temperature and 70°C. Due to a long-term drift of the electrical characteristics this type of nanocomposite cannot be used as stable temperature sensor but, after an initial burn-in procedure, a reliable operation as current limiting element has been demonstrated.File in questo prodotto:
