Summary
Polyacid-protonated covalent organic frameworks (PaCOFs) offer enhanced stability and photothermal conversion. These materials enable advanced thermal management textiles for personal cooling and heating applications.
Area of Science:
- Materials Science
- Nanotechnology
- Chemistry
Background:
- Protonation enhances light trapping and photothermal conversion in COFs.
- Conventional protonation sites in COFs suffer from environmental instability.
- This instability reduces COF stability and photothermal performance.
Purpose of the Study:
- To develop a stable protonation strategy for COFs.
- To improve photothermal conversion efficiency.
- To create advanced thermal management textiles.
Main Methods:
- In situ polymerization of dimercaptobutanesioic acid within COF pore channels.
- Formation of polyacid-protonated COFs (PaCOFs) via dynamic disulfide bonds.
- Electrospinning of PaCOFs into dual-mode thermal management textiles.
Main Results:
- PaCOFs demonstrated exceptional protonation stability.
- Achieved a superior photothermal conversion efficiency of 77.8%.
- Developed textiles provided radiative cooling (7.2 °C) and solar heating (10.1 °C).
Conclusions:
- Polyacid protonation is a robust strategy for stabilizing COFs.
- PaCOFs significantly advance photothermal energy conversion.
- PaCOF textiles offer superior performance in wearable thermal management.
