Beschreibung
Zusammenfassung:	Composite materials and methods of preparing C02 capture include: (1) a porous solid support comprising a plurality of porous channels; and (2) a nucleophilic source associated with the porous channels of the porous solid support. The nucleophilic source is capable of converting the captured C02 to poly(C02). Methods of capturing C02 from an environment include associating the environment with the aforementioned composite materials to lead to the capture of C02 from the environment. Such methods may also include a step of releasing the captured C02 from the composite material. The associating step comprises a conversion of the captured C02 to poly(C02) in the composite material. A releasing step may also include a depolymerization of the formed poly(C02). La présente invention concerne des matériaux composites servant à capturer le CO2 et des procédés pour les préparer. Les matériaux composites comprennent : (1) un support solide poreux comprenant une pluralité de canaux poreux ; et (2) une source nucléophilique associée aux canaux poreux du support solide poreux. La source nucléophilique est capable de convertir le CO2 capturé en poly(CO2). L'invention concerne également des procédés de capture de CO2 dans un environnement, les procédés comprenant l'association de l'environnement aux matériaux composites susmentionnés pour aboutir à la capture du CO2 se trouvant dans l'environnement. Ces procédés peuvent également comprendre une étape consistant à libérer le CO2 capturé par le matériau composite. L'étape d'association comprend la conversion du CO2 capturé en poly(CO2) dans le matériau composite. L'étape de libération peut également comprendre la dépolymérisation du poly(CO2) formé.
