Title:
RESPONSIVE INTERFERENCE COLORATION
Document Type and Number:
WIPO Patent Application WO/2020/142139
Kind Code:
A3
Abstract:
A three-layer system composed of a substrate, a metal or metal alloy thin film deposited on the substrate surface, and an overlaid stimulus-responsive polymer layer detects changes in environmental conditions brought about by physical, chemical, or biological stimuli. The thin metal or metal alloy film functions as an optical filter and the polymer layer changes properties (e.g., dimensions) in response to changing environmental conditions that manifests as a change in wavelength of reflected or filtered light. The system is useful in colorimetric sensors.
