Superhydrophobic, antireflective, flexible hard coatings with mechanically ultra-resilient moth-eye structure for foldable displays

Biomimicry in nanotechnology: a comprehensive review

“…The transmission property of the structures remains almost invariant under different bending, thermal, and chemical conditions. Hence, the resulting displays show very good anti-reflective function, excellent mechanical resilience, and foldability, as well as superhydrophobicity with good thermal and chemical resistance 74 .…”

Elastic broadband antireflection coatings for flexible optics using multi-layered polymer thin films

“…Conventional antireflection coatings are dominated by inorganic compounds, such as MgF 2 , Al 2 O 3 , SiO 2 , and TiO 2 . 1,4–6 Inorganic fluorides, oxides, and sulfides offer excellent transparency over a broad wavelength range, from near-UV to near-IR, and a wide range of accessible refractive indexes. Among dense films, MgF 2 possesses one of the lowest refractive indexes (∼1.38).…”

Sputtered anti-reflection layer on transparent polyimide substrate improves adhesion strength to copper layer: effects of layer thickness and sputtering power

“…The materials for transparent panel must be bendable, transparent, ultra-thin, and sufficiently stiff for the substrate. 1–4 Colorless polyimide (PI) has been regarded as the preferred material for flexible transparent panels because of its high optical transmittance, high thermal stability, low dielectric constant, and excellent resistance to chemical solvents. 3–7 However, the circuit patterns deposited on colorless PI substrates would be visible to the naked eye.…”
