Abstract
Official abstract text for this publication.
The present invention provides phosphonium ionic liquids (11) and coatings made therefrom. Highly fluorinated phosphonium ionic liquids based on (11) having been produced exhibiting high thermal stabilities, low melting points and temperature dependent solvent miscibilities. These salts and derivatives of (11) have also been employed in the preparation of superhydrophobic surfaces, indicating that ionic liquids are not only new alternative solvents, but also viable functional materials. All derivatives of (11) form biphasic systems with common laboratory solvents of ranging polarity at room temperature. Based on the solvent miscibility experiments with water and the high fluorine loading, the PILs showed obvious evidence of being hydrophobic. Coatings made with these phosphonium ionic liquids (11), salts and derivatives thereof were superhydrophobic with water contact angles were measured and all of the surfaces were determined to be superhydrophobic with contact angles >150°.
