Efficient heat dissipation by ion-mediation assembled reduced graphene oxide
A clear solution for efficient thermal management of light emitting diodes (LEDs) is elusive, which is critical for general purpose lighting. Here, a hierarchical porous structure of reduced graphene oxide through ion-mediation (IMA-rGO) is developed for efficient heat dissipation. Compared to exist...

| description | A clear solution for efficient thermal management of light emitting diodes (LEDs) is elusive, which is critical for general purpose lighting. Here, a hierarchical porous structure of reduced graphene oxide through ion-mediation (IMA-rGO) is developed for efficient heat dissipation. Compared to existing copper materials, IMA-rGO yielded the highest cooling efficiency of 36.5% through the simple and easily scalable ion-mediation process. This highly efficient heat dissipater lowered the operating temperature of a high power commercial LED from 75 °C to 59 °C, leading to a reduction in the required energy and an increase in device lifetime. With the features of a simple, scalable process and excellent heat dissipation performance, the IMA-rGO introduced here could bring LEDs closer to our daily lives. |
