Abstract

Metal corrosion causes billions of dollars of economic losses yearly. As a smart and new energy-harvesting device, triboelectric nanogenerators (TENGs) can convert almost all mechanical energy into electricity, which leads to great prospects in metal corrosion prevention and cathodic protection. In this work, flexible TENGs were designed to use the energy harvested by flexible polydimethylsiloxane (PDMS) films with ZrB₂ nanoparticles and effectively improve the dielectric constant by incorporating ZrB₂. The open-circuit voltage and short-circuit current were 264 V and 22.9 µA, respectively, and the power density of the TENGs reached 6 W·m⁻². Furthermore, a self-powered anti-corrosion system was designed by the rectifier circuit integrated with TENGs, and the open-circuit potential (OCP) and Tafel curves showed that the system had an excellent anti-corrosion effect on carbon steel. Thus, the system has broad application prospects in fields such as metal cultural relics, ocean engineering, and industry.

基于ZrB2/聚二甲基硅氧烷的高性能金属防腐摩擦电纳米发电机

金属腐蚀每年造成数十亿美元的经济损失。摩擦电纳米发电机作为一种智能的新型能量收集装置，可以将几乎所有的机械能转化为电能，在金属防腐和阴极保护方面具有广阔的前景。在这项工作中，设计了柔性Teng，以利用具有ZrB2纳米颗粒的柔性聚二甲基硅氧烷（PDMS）膜获得的能量，并通过引入ZrB2有效地提高介电常数。开路电压和短路电流分别为264 V和22.9µA，Teng的功率密度达到6 W·m−2。此外，利用集成了TENGs的整流电路设计了一种自供电防腐系统，开路电位（OCP）和Tafel曲线表明该系统对碳钢具有良好的防腐效果。因此，该系统在金属文物、海洋工程、工业等领域具有广阔的应用前景。
