Resumen
Herein, a novel superhydrophobic functionalized nano-Bi2O3 coating is designed and fabricated using electrophoretic assembly deposition (EAD) in the optimal suspension of polyethylene glycol, ethanol, acetylacetone, and surface functionalization. The small size (70 nm, nano-scale) of Bi2O3 particles and uniform distribution make the target film possessing a promising structure for realizing hydrophobic functionalization. Moreover, the hydrophobicity and stability results indicate that the product has a high-water contact angle (CA) of ca. 167° and is kept almost stable after 180 days exposure in the natural environment. These findings will provide new insight into a better design of superhydrophobic functional coatings via this facile method, holding great promise for future various applications.
