Project Description


Project description:

Low-maintenance, easy-clean surfaces reduce chemicals, energy use, and downtime across different industries. Superhydrophobic (and application-tuned superoleophilic/underwater-oleophobic) coatings enable simple, gravity-driven oil/water separation and self-cleaning, but many high-performance systems rely on fluorinated chemistries. To align with sustainability goals, we target fluorine-free coatings that retain high wetting performance and durability on robust substrates.

In the Functional Materials for Food Packaging group, we take a bio-inspired approach – creating lotus-like surfaces by forming nanostructured polyalkylsiloxane (PASO) networks from non-fluorinated organosilanes on metals, PET, or glass fiber. By tuning the roughness and surface energy, we aim for high water contact angles, low hysteresis, and low sliding angles.

In this project, the student will formulate silane sols (amine-/epoxy-/acrylate-terminated), deposit coatings by dip/spray/spin coating, and engineer hierarchical textures (e.g., nanoparticle-assisted or phase-separation routes). To this end, we will characterize the surfaces for their wetting properties, morphology (SEM), and chemistry (FTIR), to then demonstrate functionality in a simple, gravity-driven oil/water separation test on coated meshes. Finally, the durability of the coatings will be assessed and regeneration strategies for circular use will be explored.
