Biomimetic non-iridescent structural color materials from polydopamine black particles that mimic melanin granules

摘要

A novel approach for creating non-iridescent bright structural color materials from polydopamine (PDA) black particles is presented. Two biomimetic features, melanin granules and the amorphous structures found in nature, were incorporated into these materials, consisting of PDA black particles to develop a bright and non-iridescent structural color without using any additives.
