Photonic Multilayer Sensors from Photo-Crosslinkable Polymer Films

Colorimetric temperature sensors are prepared from photo‐crosslinkable polymers by sequentially spin‐coating and crosslinking alternating layers of poly(N‐isopropylacrylamide) and poly(para‐methyl styrene). Layer thicknesses and copolymer chemistries are chosen to provide robust colorimetric tempera...

Description
Summary:Colorimetric temperature sensors are prepared from photo‐crosslinkable polymers by sequentially spin‐coating and crosslinking alternating layers of poly(N‐isopropylacrylamide) and poly(para‐methyl styrene). Layer thicknesses and copolymer chemistries are chosen to provide robust colorimetric temperature sensors that cover nearly the full visible spectrum.
