| contents | OSTE Superhydrophobic Synthetic Paper (SUSP) with Superior Plastron Stability by Capillary Effect. Li, Haonan Zhong, Jiahua He, Qinghao Zhang, Huiru Ting Chu, Lok Zhang, Xingwei Guo, Weijin Inspired by the air transport system in submerged lotus roots, we develop a superhydrophobic synthetic paper (SUSP) based on an off-stoichiometry thiol-ene (OSTE) polymer, capable of sustaining a stable underwater plastron through spontaneous capillary-driven air replenishment. The material is fabricated by coating a lithographically patterned interlocked micropillar array (synthetic paper) with a hydrophobic spray, yielding a porous, low-cost surface with a water contact angle of 155.2° ± 1.6° and a sliding angle of 3.8° ± 0.3°. When partially exposed to air, SUSP rapidly restores a depleted plastron in sub-second timescales (e.g., 0.23 s for a 0.5 cm wide sample) and maintains full plastron coverage for over 12 h in degassed water, significantly outperforming fully submerged controls. Parametric studies reveal that plastron recovery kinetics depend on capillary width, immersion depth, and liquid surface tension. SUSP also demonstrates practical functionalities: it enables efficient underwater bubble collection, directional transport, and reduces hydrodynamic drag by up to 4.3% by preserving a continuous air layer under flow. Even in mud-rich environments, SUSP retains its superhydrophobicity, highlighting its robustness for applications in marine antifouling, drag reduction, and underwater gas management. This work presents a biomimetic, passive strategy for achieving durable and self-replenishing superhydrophobicity in submerged conditions. |
