AI Article Synopsis
- Researchers developed high-performance, flexible, transparent heaters using large-scale graphene films made via chemical vapor deposition.
- The graphene heaters exhibit low sheet resistance of ∼43 Ohm/sq and high optical transmittance of ∼89%, outperforming traditional indium tin oxide heaters in both temperature control and heat distribution.
- These heaters maintain efficiency even under mechanical strain (up to ∼4%) and have potential applications in areas like automobile defogging and heatable smart windows.
Article Abstract
We demonstrate high-performance, flexible, transparent heaters based on large-scale graphene films synthesized by chemical vapor deposition on Cu foils. After multiple transfers and chemical doping processes, the graphene films show sheet resistance as low as ∼43 Ohm/sq with ∼89% optical transmittance, which are ideal as low-voltage transparent heaters. Time-dependent temperature profiles and heat distribution analyses show that the performance of graphene-based heaters is superior to that of conventional transparent heaters based on indium tin oxide. In addition, we confirmed that mechanical strain as high as ∼4% did not substantially affect heater performance. Therefore, graphene-based, flexible, transparent heaters are expected to find uses in a broad range of applications, including automobile defogging/deicing systems and heatable smart windows.
