Selective Polymer Distributed Bragg Reflector Vapor Sensors. [PDF]
Polymers (Basel), 2018 We report on Flory–Huggins photonic sensors for the selective detection of volatile organic compounds without the use of any chemical functionalization. For this purpose, we employed periodic multilayers made of inert cellulose acetate alternated to active polystyrene films whose free volume was modified with silanized ZnO nanoparticles.
