Area of Science:

  • Materials Science
  • Surface Chemistry
  • Textile Engineering

Background:

  • Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are effective waterproofing agents but pose environmental risks.
  • Developing sustainable, fluorine-free alternatives with comparable performance is a critical challenge.
  • Existing fluorine-free coatings often lack the efficiency and durability of PFAS-based treatments.

Purpose of the Study:

  • To enhance the hydrophobicity of biobased, fluorine-free coatings on polyester textiles.
  • To investigate the effect of multiscale surface topography on water repellency.
  • To develop a scalable and environmentally responsible method for creating advanced functional textiles.

Main Methods:

  • Fabrication of textiles with nanopillared arrays using nanogravure printing, superimposed on inherent fabric roughness.
  • Analysis of surface topography across multiple scales using "Wenzel spectroscopy."
  • Characterization of water droplet behavior (contact angle, pinning) to assess water repellency and surface wetting regimes.

Main Results:

  • Multiscale surface design significantly boosted the hydrophobicity of a fluorine-free coating (Lamoral A5).
  • Nanostructuring shifted smoother fabrics from the Wenzel to the Cassie-Baxter wetting regime, increasing contact angles by 5-10°.
  • The submicrometer component of surface roughness was identified as critical for improving water repellency in smoother fabrics.

Conclusions:

  • Hierarchical surface structuring, mimicking natural superhydrophobic surfaces, is an effective strategy for enhancing fluorine-free textile coatings.
  • The developed nanostructuring technique is scalable and environmentally responsible, offering a sustainable route to high-performance textiles.
  • This approach provides a viable alternative to PFAS for durable, water-repellent textiles in outdoor and protective applications.
