Abstract

Abstract Epoxy resin based on carbon nanotubes with heating properties is studied to tune its heating performance by changing the applied voltage value. The developed self‐heating device, able to heat to high temperatures in a short time, can be applied in various areas. The electro‐thermal investigation shows the presence of both positive temperature coefficient (PTC) and negative temperature coefficient (NTC) behaviors with a predominance of NTC trend neat to the glass transition temperature of the epoxy matrix.
