Abstract A self-organizing structure is important for imparting functions and simplifying the manufacturing process.The development of spontaneous structures with a roll-to-roll process capability is echofix spring reverb a challenging task.We propose a novel patterning method utilizing the destruction of the emulsion structure.An oil-in-water (O/W) UV-curable emulsion liquid film was partially exposed to UV, resulting in aggregation and immobilization of the emulsion in the medium.Emulsion droplets in the unexposed area are coalesced by removing water.

Coalesced emulsion droplets expand and spontaneously permeate into the pores formed in the aggregated structure of UV-cured emulsion particles, causing an uneven structure.An uneven pattern can be formed by direct UV exposure of read more the liquid film and the subsequent drying process without requiring a development process.
