Temperature self-regulating flat electric heaters based on MWCNTs-modified polymers (Nov, 10.1007/s00289-020-03483-y 2020)

Abstract

This article describes a technique for the manufacturing of the composites MWCNTs-modifed elastomers. The efect of the diferent MWCNTs mass contents in the

elastomer on specifc volume and surface electrical resistivity values was investigated. The results on the heaters based on the elastomers and altered with multiwalled carbon nanotubes (MWCNTs) over various catalysts are discussed. It was

found that with an increase in the MWCNTs mass content, the maximum power is

achieved at a lower voltage value. Besides, temperature felds were measured on the

surface of heater samples, and it was established that the temperature variation on

the sample surface did not exceed 5 °C, and the heaters had a heating rate of 0.2–

0.5 °C/s. Furthermore, a comparison of these heaters with the analogs previously

reported by the other researchers is presented, indicating good importance of the

reported work. The industrial (commercial) production of such devices is mainly

associated with using in fan heaters for domestic purposes, in heaters built into

clothes in underfoor heating systems and motor vehicles. The present work will fnd

a good industrial application in the future.
