Angle-Independent Structural Colors for Personal Thermal Management

Recently, bottom-up assembly of colloidal particles into structural colors represent a major research interest of optical devices for coating, sensing, and display. Despite much breakthroughs in the preparation of structural colors, the film forming strategy is still highly relied on conventional evaporation-induced processes. Herein, inspired from membrane separation processes, we develop a membrane separation-assisted assembly (MSAA) strategy for the preparation of angle-independent structural colors. The process is carried out by separating between water and solid particles in colloidal latex, allowing them to facilely form amorphous structures with robust functions.
