Preparation of robust anti-smudge coatings via electrophoretic deposition

• A robust anti-smudge coating was fabricated using a water soluble precursor.
• EPD was demonstrated as a new strategy for preparing anti-smudge coatings.
• The coating provides substrates with excellent protection.

Anti-smudge (oil- and water-repellent) coatings that incorporate low surface energy components are typically prepared from solvent-based precursors. Herein, we demonstrate for the first time, a robust and smooth anti-smudge coating that can be fabricated using a water-soluble precursor. Furthermore, the solubility of the novel precursor provides this aqueous electrophoretic deposition strategy with potential as a new strategy for the preparation of anti-smudge coatings for conductive substrates. The coating has outstanding durability, it provides substrates with excellent protection against exposure to harsh conditions, and it can be prepared in various colors. This newly developed strategy can be readily applied onto a diverse range of conductive substrates.
