Summary
Researchers developed a new durable superamphiphobic fabric coating using perfluoroalkyl acrylate, silane, and silica nanoparticles, enhanced by argon-plasma treatment. This robust coating repels water and oil, resisting laundry and abrasion for practical applications.
Area of Science:
- Materials Science
- Surface Chemistry
- Textile Engineering
Background:
- Developing durable superamphiphobic surfaces is crucial for applications requiring liquid repellency.
- Existing methods often lack long-term stability against mechanical and chemical challenges.
Purpose of the Study:
- To report a novel method for creating highly durable superamphiphobic fabrics.
- To evaluate the performance and stability of the developed coating.
Main Methods:
- Preapplying a solution of perfluoroalkyl acrylate, epoxide-containing silane, and silica nanoparticles onto fabric.
- Subjecting the coated fabric to subsequent argon-plasma treatment.
Main Results:
- The coated fabrics exhibited superamphiphobicity, repelling both water and oil (surface tension >21.5 mN m⁻¹).
- The superamphiphobicity remained intact after repeated laundry cycles and abrasion.
- The coating demonstrated excellent stability in boiling water, strong acids, and bases.
- The fabric's handle and air permeability were minimally affected.
Conclusions:
- The argon-plasma-enhanced coating provides a facile and effective route to durable superamphiphobic fabrics.
- This method offers a promising solution for creating high-performance repellent textiles.
