Graphene-based heater

Paper in proceedings, 2016

The excellent thermal conductivity and optical transmittance of graphene make it tremendously interesting as a material for heating applications. In this paper, we demonstrate graphene can be used as a new heating element. The graphene is synthesized by chemical vapor deposition (CVD) on Cu foil. The heating performance is studied in terms of applied voltage, heating rate and input power density. A two-layer graphene film based heater can reach an equilibrium temperature up to 90C when 60 V voltage is applied for 2 min. A maximum heating rate of 1.1 C/s was observed under an applied voltage of 60 V. The results indicate that the graphene-based heater holds great promise for many applications such as defrosting and antifogging devices.
