Multi-F-Structured MOF Materials Enhance Nanogenerator Output Performance for Corrosion Protection of Metallic...

Area of Science:

• Materials Science
• Nanotechnology
• Electrochemistry

Background:

• Metal-organic frameworks (MOFs) offer tunable porous structures and high surface areas, making them promising functional materials.
• Triboelectric nanogenerators (TENGs) efficiently convert mechanical energy into electrical energy, with MOFs being explored for TENG applications.

Purpose of the Study:

• To investigate the impact of fluorine (F) content on the microstructure and performance of MOFs in TENGs.
• To develop self-powered corrosion protection systems using MOF-based TENGs.

Main Methods:

• Synthesized two MOFs with similar spatial structures but differing F content.
• Characterized the microstructural modulation based on F content.
• Evaluated the output performance of the MOFs as friction materials in TENGs.
• Assessed the corrosion protection capabilities of the MOF-based systems.

Main Results:

• The end microstructures of the MOFs were successfully modulated by varying F content.
• Friction power generation performance increased with higher F content.
• The developed polyacidic ligand materials demonstrated effective self-powered corrosion protection for metallic materials.

Conclusions:

• Fluorine content is a critical factor in tuning MOF microstructures for enhanced TENG performance.
• MOF-based TENGs show significant potential for constructing efficient self-powered corrosion protection systems.
