A single-walled carbon nanotube (SWCNT) film was formed on a glass substrate by using the dip-coating method and the resulting material used as a transparent glass heater. The heaters have an optical transparency above 95% in visible light. Their performance was investigated by measuring their heating/cooling characteristics and thermal resistance. They have a heating performance that is ∼70% higher than that of Pt film heaters, which are widely used. The thickness dependence of the thermal resistance is observed, and can be understood in relation to heat-transfer losses that are related to the porous structure of the SWCNT film. The stability and reliability of the heater were also investigated.
