A Supraparticle-Based Approach to Robust Biomimetic Superhydrophobic Coatings.

ABSTRACT: Repellent surfaces provide resistance to biofouling, ice formation, bacteria adhesion, or corrosion. Inspired by the hierarchical structure of the lotus leaf, such surfaces minimize water adhesion through micro- and nanostructuring. Conventional fabrication methods to mimic the lotus leaf often involve problematic fluorinated compounds, sophisticated preparation conditions, or lack mechanical robustness. This study presents a fluorine-free, scalable approach for fabricating durable superhydrophobic coatings using supraparticles. Supraparticles are structured aggregates of colloidal primary particles and serve as intermediate building blocks that provide hierarchical surface roughness. These supraparticles are fabricated by spray drying and introduce hydrophobic surface properties via alkyl
