POLYMER AND CARBON NANOTUBES COMPOSITE MATERIALS AS LOW-COST TEMPERATURE SENSORS

摘要

The invention concerns a system based on polymeric composites with carbon nanotubes to obtain low-cost and high accuracy temperature sensors. The composite material is obtained by homogeneously dispersing a suitable amount of carbon nanotubes having conductive characteristics within a polymer matrix. The sensing device is obtained by connecting at least two electrodes to the polymer-carbon nanotubes composite and measuring the electrical resistance of the system obtained. The composite material and the articles consisting of the said material can be applied in all those situations requiring a low-cost sensor having even complex geometrical shape.
