Title:
BIOLOGICALLY-INSPIRED COMPOSITIONS THAT ENABLE VISIBLE THROUGH INFRARED COLOR CHANGING COMPOSITIONS
Document Type and Number:
WIPO Patent Application WO/2019/139649
Kind Code:
A3
Abstract:
Biologically-inspired compositions, including color changing compositions, and corresponding embodiments such as sensors, textile materials, coatings and films, are provided which typically include a solid, transparent and nondegradable matrix. The matrix contains a plurality of (i) synthetic particles having a size in the micrometer or nanometer range, each synthetic particle including one or more aggregates of a pigment selected from phenoxazone, phenoxazine, and a derivate or precursor thereof, and a stabilizing material which has a refractive index larger than 1.45, the aggregates having a size larger than about 100 nm; or (ii) submicrometer natural particles extracted and purified from homogenized tissue.
