Fabrication of Self‐Wrinkling Polymer Films with Tunable Patterns through an Interfacial‐Fuming‐Induced Surface Instability Process (Small 19/2024)

Self-Wrinkling Polymer Films In article number 2311679, Han-Yu Hsueh and co-workers were inspired by the superglue fuming method for fingerprint collection and developed a novel interfacial-fuming-induced surface instability process to generate wrinkled patterns on polymeric substrates. The technique can be easily applied to architectures with complex outer morphologies and inner surfaces and has considerable potential for use in various practical applications, including microfluidics, optical components, bioinspired adhesive devices, and interfacial engineering.
