Compositions are provided herein comprising a base material having engrafted polymer brusches. The polymer brushes further comprise one or more functional groups immobilized along the surface of the brushes in a plurality of layers, which confer functional properties to the base material compositions. Methods of using these compositions include deoxygenation of a sample solution, hydrolyisis of denaturing agents in a sample solution, resolution of racemic mixtures in a sample solution, and purification and concentration of target compounds.
L'invention concerne des compositions comprenant une matière de base avec des brosses polymères greffées. Les brosses polymères comprennent également un ou plusieurs groupes fonctionnels immobilisés sur la surface des brosses dans une pluralité de couches, conférant des propriétés fonctionnelles aux compositions contenant la matière de base. Les méthodes d'utilisation de ces compositions consistent à procéder à la désoxygénation d'une solution échantillon, à l'hydrolyse d'agents de dénaturation de la solution échantillon, à la résolution de mélanges racémiques dans la solution échantillon, et à la purification et à la concentration des composés cibles.
