Controllable Triboelectric Series Using Gradient Positive and Negative Charge-Confinement Layer with Different Particle Sizes of Mesoporous Carbon Materials |
| 초록 |
As a method to maximize the energy efficiency of triboelectric nanogenerators (TENGs), High-Voltage Charge Injection (HVCI) is a simple and effective method for increasing both the positive and negative surface charge densities. In this study, positive and negative triboelectric series were controlled using a 3-layer gradient charge-confinement wherein the particle sizes of the mesoporous carbon spheres (mCSs) were sequentially arranged depending on the external surface area of the mCSs. In the gradient charge-confinement layers of this study, the mCS with differently sizes performed charge transport from the surface to a deep position during HVCI while mitigating the charge loss through charge confinement to induce the high space charge densities. Through this process, the output voltage—which was initially 15.2 V—was measured to be 600 V after HVCI. |
