Long‐Term Immersion Study for Durability of Interconnected Micropatterned Surfaces with Sustained Water Repellency (Adv. Mater. Interfaces 22/2024)

Long-Term Water Resistance Stability In article 2400144, Seok Kim, Young Tae Cho, and co-workers show the variation in contact angle based on the pattern when two water-repellent surfaces, one consisting of a Hexagon Grid Pattern (HGP, on the right) and the other a Hierarchical Hexagon Grid Pattern (H-HGP, on the left), are immersed in water and subsequently removed. Upon removal from water, the HGP retains its hydrophobic properties, whereas the H-HGP transitions to hydrophilic.
