We report the fabrication of a sticky superhydrophobic paper surface with extremely high contact angle hysteresis: advancing contact angle ∼150◦ (superhydrophobic) and receding contact angle ∼10◦ (superhydrophilic). In addition, we report the controlled tunability of the contact angle hysteresis from 149.8 ± 5.8◦ to 3.5 ± 1.1◦, while maintaining superhydrophobicity, as defined through an advanc...
