Colloidal Crystal Patterns: Tunable Colloidal Crystalline Patterns on Flat and Periodically Micropatterned Surfaces as Antireflective Layers and Printable–Erasable Substrates (Adv. Mater. Interfaces 11/2018)

Abstract

Tunable non‐close‐packed colloidal crystal patterns with disk‐like or hemispherical colloidal shapes, formed by exposing close‐packed colloidal crystal to aqueous salt solution, are achievable on various flat and periodically micro‐patterned substrates. Also, inorganic‐polymer hybrid colloidal crystal patterns can be readily prepared. These colloidal patterns are useful as anti‐reflective layers and printable‐erasable substrates. This is reported by Ji Eun Song, Eun Chul Cho, and co‐workers in article number https://doi.org/10.1002/admi.201800138.

Self-Erasable Nanocone Antireflection Films Based on the Shape Memory Effect of Polyvinyl Alcohol (PVA) Polymers

“…A lot of properly arrays nanostructures have been designed and fabricated, such as nanodomes [3], nanospheres [4,5], nanocones [6,7], nanowires [8], nanopillars [9], and nanopyramids [10]. Various researches have been reported on patterning nanostructures using the metals, glass, semiconductor, and polymers materials substrates for effectively reducing optical reflection [11,12,13,14]. Optical polymer materials as substrate have attracted more attention due to their flexible optical properties, low cost, and easy processing.…”
