Stretchable polymeric-gel-based sponge with tunable wettability via segmented network design

Abstract

A polymeric-gel-based sponge with robust stretchability and tunable wettability is developed. Unlike conventional sponges, its wettability is permanently tailored during synthesis. This transparent, mechanically stable material is applicable in oil/water separation systems and stretchable electronics, offering a promising approach for next-generation functional sponges with adaptable and stable surface properties.
