Title:
COLORIMETRIC PHOTONIC CRYSTAL STRUCTURE AND COLORIMETRIC PHOTONIC CRYSTAL SENSOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/066941
Kind Code:
A1
Abstract:
The present invention relates to a colorimetric photonic crystal structure comprising a high-refractive index layer using a copolymer simultaneously comprising a repeat unit containing a quaternary ammonium ion and a repeat unit derived from an acrylate- or acrylamide-based monomer having a photoactive functional group. The colorimetric photonic crystal structure can perform a color conversion, which is visually recognizable according to the humidity change, and can be used to manufacture a photonic crystal sensor. In addition, the present invention is directed to a method for manufacturing a colorimetric photonic crystal structure, the method comprising a step for quaternizing nitrogen atoms present in the repeat units of the copolymer included in one layer that are repeated, and a colorimetric photonic crystal structure with a reflection wavelength to be realized can be manufactured by controlling quaternization reaction conditions.
