Smart surfaces with adjustable wettability are gaining significant interest in both foundational research and industrial applications, where control over surface interactions with liquids is essential. The wettability of solid surfaces depends mainly on their chemical composition and surface topography. These nanofibers were then used to create superhydrophobic coatings, which were applied via a room-temperature spraying technique. The resulting coatings demonstrated dual-responsive wettability, enabling a reversible switch between superhydrophobic and hydrophilic states. Meanwhile, applying an electric stimulus caused a shift in surface wettability through the redistribution of charges and the alignment of electric dipoles along the liquid–solid interface.
