Transparent heaters based on CVD grown few-layer graphene
Artikel i vetenskaplig tidskrift, 2022

The outstanding thermal and optical properties of graphene make it tremendously interesting as heating elements. In this work, we demonstrate few-layer graphene as heating elements on glass substrate by chemical vapor deposition (CVD) method combined with a layer-by-layer transfer process. The electrothermal performance was studied in terms of applied voltage, heating/cooling rate and input power density. The results show that a three-layer graphene film heater can reach an equilibrium temperature up to 102 °C and a maximum heating rate of 1.8 °C/s when 60 V voltage was applied. Simulations were further performed to rationalize the experimental results, in which the effect of heat transfer coefficient, electric conductivity, and the effective stress distribution was discussed. It was found that the adhesion between graphene and substrate is very important for the heat performance, especially at high temperatures. Our results indicate that graphene-based films are promising candidate materials for the next generation of transparent heating elements.
