摘要
TENGs 能够将机械能转化为电能,因此备受关注。金属有机框架(MOFs)等材料和器件结构的进步提高了其性能。我们利用第一性原理理论设计了纳米发电机,并研究了无氨基官能化 Zn-MOF(NH2- Zn-MOF)的新型三电性能。氨基官能化具有非常规的静电功能,会改变表面电势、功函数和电容。胺官能化的 Zn-MOF V 型 TENG 器件达到了 624 V 的最大峰-峰电压和 244 mW/m2 的最大功率密度。胺功能化使输出性能比未功能化器件提高了 2.5 倍。收集的能量可用于电容器充电和为低功率电子设备供电。此外,氨基官能化 MOF-TENG 器件被证明是一种很有前途的智能运动传感器,可用于检测和监控。
Development of New Amine-Functionalized Metal-Organic Framework for Enhanced Triboelectrification Using First-Principle Theory of Nanogenerator
TENGs have gained significant attention due to their ability to convert mechanical energy into electricity. Advancements in materials like metal-organic frameworks (MOFs) and device architecture have led the improvements in performance. We used a first-principle theory nanogenerator to design and investigate the novel without and with amino-functionalized Zn-MOF (NH2- Zn-MOF) for the triboelectric properties. The amino functionalization possesses unconventional electrostatic functions with the change in the surface potential, work function and capacitance. V-shaped amine-functionalized Zn-MOF TENG device achieved a maximum peak-to-peak voltage of 624 V along with a maximum power density of 244 mW/m2. The amine functionalization results in a 2.5-fold increment in output performance than the non-functionalized device. The harvested energy is utilized for capacitor charging and powering low-powered electronics. Furthermore, the amino-functionalized MOF-TENG device proves as a promising smart sports sensor in detection and monitoring.
