Abstract
This paper reports the resistance change of conductive carbon nanotube (CNT) thin-films according to the temperature variation. Resistance of conductive CNT thin-films intrinsically has good thermal sensitivity, but shows environmental dependency. In order to reduce environmental effects, we spin-coated polydimethylsiloxane (PDMS) on the conductive CNT thin-films. We observed that conductive CNT thin-films with a PDMS encapsulation layer showed little environmental dependency, but more linear and stable temperature dependencies. If proper encapsulation is provided, conductive CNT thin-films can be used for temperature sensor applications.
