Abstract: Polymer Journal, Published online: 16 October 2026; doi:10.1038/s41428-026-01262-6A simple method for expanding the Bragg reflection width of elastomer-immobilized, nonclose-packed colloidal photonic crystal films using a mixture of two types of elastomer precursors was proposed. For the elastomer-immobilized, nonclose-packed colloidal photonic crystal film exclusively prepared using 4-hydroxybutyl acrylate (4HBA), the full width at half maximum of the Bragg reflection peak was 19 nm; this val[...]


Our summary: A method for expanding the Bragg reflection width in elastomer-immobilized colloidal photonic crystals was developed using a binary mixture of elastomer precursors. The addition of 2-hydroxyethyl methacrylate significantly increased the Bragg reflection peak width from 19 nm to 186 nm. This technique aims to enhance the use of these crystals in structural color applications and optical filtering.

Autonomous physics-guided discovery of functionally graded metamaterials

Published on 2026-09-21 by @OXFORD

Abstract: AbstractDesigning functionally graded lattices requires control of the architecture under complex loading, yet conventional workflows often rely on static datasets and sequential simulations.
