Patent ID: 8562856

Claim:
A getter system for sorption of one or more gases, consisting of: a polymer selected from polyacrylates and polymethacrylates, polyetherimide (PEI), polyamides (PA), cellulose acetate (CA), tri-cellulose acetate (TCA), polysiloxanes, polyvinylalcohols (PVAL), polyethyleneoxide (PEO), polyethyleneglycol (PEG), polypropyleneglycol (PPG), polyvinylacetate (PVAC), co-polymers of polyethylene-vinylalcohol and copolymers of PA-PEO and polyurethanes-PEO; a powder of a porous material distributed in the polymer, wherein the porous material is selected from natural or synthetic zeolites, silicalites, aluminosilicates, fullerenes and metal-organic frameworks; a phase active in the sorption of the one or more gases, wherein the phase is dispersed in pores of the porous material; wherein the system maintains transparency on variations of amount of the at least one sorbed gas, wherein the polymer is permeable to the at least one gas to be sorbed and is amorphous, and wherein the powder of porous material distributed in the polymer has a mean particle size of less than 100 nanometers, and optionally inside the pores, catalysts capable of accelerating reactions between the at least one gas to be sorbed and the active phase, and optionally a surfactant; wherein: when the at least one gas to be sorbed is oxygen, the active phase is selected from easily oxidizable metals, metal oxides having low oxidation state, and salts with phosphite or phosphonite anion; when the at least one gas to be sorbed is carbon monoxide, the active phase is selected from nickel, iron, alkenes, amines, and ketones, the ketones being in the presence of lithium-based organometallic compounds; when the at least one gas to be sorbed is carbon dioxide, the active phase is a hydroxide of an alkaline or alkaline-earth metal; when the at least one gas to be sorbed is nitrogen, the active phase is selected from lithium, barium, the compound HaLi 4 and porphyrins, and when the at least one gas to be sorbed is water, the active phase is selected from epoxides, alkaline metal oxides, compounds forming carbocations; alkaline-earth oxide metals or oxides of metals selected from nickel, zinc and cadmium; organic and inorganic anhydrides; alkoxides; hydrolyzable inorganic halides and acylic halides; mixtures of iron with another element selected from yttrium, palladium, and mixtures thereof; and magnesium sulphate.
