Abstract: 
Fabrics with special wettability have drawn growing attention in recent years in the area of oil–water separation due to their low cost, good flexibility, and ease of handling. However, an efficient and fast method to enable the required wetting state on fabrics still remains a challenge. In this work, a one‐step, rapid, and chemical‐free hydrogen plasma treatment is reported to prepare a superhydrophobic and oleophilic polyester fabric. The as‐prepared fabrics display a static water contact angle of 153.2° with excellent oil–water separation capability. The mechanism of surface transformation is discussed through chemical analyses, which indicate a significant removal of carboxyl group from the pristine hydrophilic surface. This developed method is envisaged to be used for on‐demand large‐scale production of materials for emergency oil cleanup through either separation or selective adsorption.
