Abstract[English]
A sorbent for direct air capture of CO2 includes a porous amine-functionalized polymeric material including a backbone and a plurality of side chains having amine groups branching from the backbone, the backbone including a rigid crosslinker having crosslinker groups, a ratio of the crosslinker groups to a total number of monomer repeating units in the polymeric material is about 0.1 to 0.4 such that the polymeric material's internal surface area is about 10 to 500 m2/g.[French]
L'invention concerne un sorbant pour la capture directe du CO2 dans l'air comprend un matériau polymère poreux fonctionnalisé à l'amine comprenant une chaîne principale et une pluralité de chaînes latérales comportant des groupes amines ramifiés à partir de la chaîne principale, la chaîne principale comprenant un agent de réticulation rigide comportant des groupes réticulants, le rapport entre les groupes réticulants et le nombre total d'unités répétitives monomères dans le matériau polymère étant d'environ 0,1 à 0,4, de sorte que la surface interne du matériau polymère soit d'environ 10 à 500 m2/g.
