Superhydrophobicity and underwater superoleophobicity demonstrate mutual advantages in various water-related interfacial applications. However, achieving such two opposite superwetting states on a single one-fabric surface without introducing any continuous external stimulus remains a great challenge. In this work, a chemical vapor deposition (CVD) modification methodology for achieving superhydrophobicity and underwater superoleophobicity on a single one-fabric surface is presented. The CVD methodology plays a crucial role in realizing such unusual superwetting properties that can be achieved through a moderate synergetic effect from hydrophobic and hydrophilic components in surface chemistry. Driven only by gravity, the as-prepared fabric with reasonable resistance to repeatable laundering cycles and long-time corrosive liquid submersion can be further applied in high-efficiency on-demand oil−water separation
