Synthèse de cristaux photoniques modulables à partir de films minces d’hydrogel stimulables

Abstract : Research in the field of synthetic photonic crystals has been advancing at high speed. In thedevelopment of this field, additional performances in terms of modularity and switchabilityusing soft matter and polymers provide unprecedented enhanced devices. In this thesis, wedeveloped a platform of stimuli-responsive nano- and microstructured polymer hydrogelsthat are surface-grafted to ensure chemical stability regardless of environmental change.This strategy is based on CLAG chemistry which consists in simultaneous Cross-Linking AndGrafting of polymer chains on the substrate. This platform is exploited to fabricate stimulableBragg mirrors with large amplitude of spectral shift. We also developed a strategy allowingus to design two-dimensional photonic cristals by using photolithographic masks. Finally, wedemonstrated that the hydrogel platform allows the coupling of temperature with otherstimuli: chemical, mechanical, light and electromagnetic field for plasmonic and magnetichyperthermia.
