An Adaptable Charge Source Enabled by Mode‐Switchable TENG for Efficient Self‐Repairing Coating

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(30)

Published: March 28, 2024

Abstract Self‐repairing coatings have received widespread attention due to their ability repair damaged surfaces. However, film‐forming molecules can only be fixed on the metal surface through relatively weak physical and chemical adsorption. This drawback limits its self‐repairing ability. Here, a mode‐switchable TENG (MS‐TENG) is developed, which has switch between AC DC outputs as an adjustable charge source for coatings. Besides normal sector electrodes of rotational TENG, MS‐TENG special design external (small extension rotator inner/outer orbit stator) achieves accumulation excitation circuit output air breakdown with advantage complete release accumulated charges. Compared traditional current been improved. In addition, process occurs in electrode framework independent body. Therefore, negative impact suppressed. Finally, used achieve rapid electrostatic adsorption charged injection. effectively improves performance coatings, corrosion inhibition rate 96.9%.
