Abstract Stretchable surfaces with site-selective and degree-controlled wettability are indispensable for various applications ranging from self-cleaning to droplet manipulation and drag reduction; however, superwettable surfaces or patterns with robust stretchability are seldom demonstrated to date. To address such challenging issue, herein, we proposed a facile approach to programmatically realize extreme wetting-contrast patterning of stretchable carbon nanotubes/polydimethylsiloxane (CNTs/PDMS) using atmospheric micro-plasma jet (μPJ). The μPJ had been used to engineer both superhydrophobicity and superhydrophilicity through exploiting surface hierarchical roughness under a shielding nitrogen gas and oxygenic functional groups in atmosphere, respectively, tailoring the water contact angles from ~160° to
