Title:
CHROMOGENIC MATERIALS, METHODS OF MAKING CHROMOGENIC MATERIALS, AND METHODS OF USE
Document Type and Number:
WIPO Patent Application WO/2020/027871
Kind Code:
A3
Abstract:
The present disclosure provides for porous polymer materials that include an ordered array of voids separated by a polymer framework. The porous polymer material can have a recovery state where the voids are in an uncollapsed state and iridescent color, and a deformed state having voids in a collapsed state that is non-iridescent or substantially transparent. The materials can have regions of both states simultaneously. Also described are methods for fabricating a polymer material as above, as well as chromogenic sensors including the polymer material. The sensors can have hidden anti-counterfeiting patterns, hydrophobic/oleophobic properties, and chromogenic transformation can be triggered by various stimuli such as solid target compounds, light energy, and more.
