Abstract

L'invention concerne des systèmes réversibles d'hydrogel. En particulier, ledit hydrogel comporte des copolymères pouvant être un hydrogel sous une forme oxydée et un solution sous une forme réduite. Une solution du copolymère peut être oxydée de façon à former un hydrogel et l'hydrogel peut être réduit de façon à former une solution du copolymère. Des nanogels réversibles peuvent être formés aussi à partir d'une solution diluée des copolymères. L'hydrogel est formé avec des nano-particules noyées dans celui-ci de façon à former un nanocomposite dont l'indice de réfraction et le module peuvent être contrôlés en modifiant les quantités de nano-particules et la concentration de polymère de l'hydrogel respectivement.
