Abstract

The invention discloses an organic amino supported metallic organic framework-porous polymer composite material. The material consists of organic amino, a metallic organic framework material and a porous polymer of multi-stage pore structures which are mutually communicated, wherein metallic organic framework crystal granules are embedded into pore wall surfaces of pore walls of the porous polymer; the organic amino is bonded with the pore wall surfaces of the porous polymer through chemical bonds and bonded with the surface of the metallic organic framework through chemical bonds or coordination bonds; the composite material has a specific surface area greater than or equal to 50m<2> / g. The invention further provides a preparation method of the organic amino supported metallic organic framework-porous polymer composite material. The preparation method comprises the following three steps: carrying out high inner phase emulsion template crosslinking copolymerization, carrying out MOF (Metallic Organic Framework) in-situ growth or MOF multi-time growth, and carrying out organic amino supporting. The organic amino supported metallic organic framework-porous polymer composite materialdisclosed by the invention is used for capturing and separating CO2 and has the advantages of being high in CO2 adsorption capacity / velocity / selectivity, rapid in desorption speed, high in adsorption / desorption circulation stability, excellent in high-temperature and moisture resistance, and the like.

Description

technical field [0001] The invention belongs to the field of functional polymer composite materials, and in particular relates to a metal-organic framework-porous polymer composite material supported by an organic amine, a preparation method and application thereof. Background technique [0002] With the progress of the country's industrialization process, energy consumption shows an explosive growth trend. In today's energy structure, fossil fuels account for 85% of total energy consumption, accompanied by a large amount of greenhouse gas CO 2 emissions. Atmospheric CO 2 The concentration has changed from 550mg / m in 1900 3 Increased to 764.4mg / m in 2004 3 , and is still increasing. my country's current CO 2 Emissions rank second in the world and are still growing rapidly. my country is bound to become the world's CO2 2 The focus of emission reductions is under increasing international pressure. To control CO in the air 2 Concentration, carbon dioxide capture storag...
