Abstract
Methods of making a poly(propylenimine) (PPI) sorbent, a PPI sorbent, structures including the PPI sorbent, methods of separating CO2 using the PPI sorbent, and the like, are disclosed.
Claims24
A material comprising:
- a porous structure having supported thereon at least one of:
- a) a poly(propylenimine) (PPI) sorbent, wherein the PPI sorbent is in a plurality of pores of the porous structure, wherein the PPI sorbent comprises a linear PPI, a dendritic PPI, or both the linear PPI and the dendritic PPI;
- b) a poly(propylenimine) (PPI) sorbent, wherein the PPI is physically impregnated in the porous structure and not covalently bonded to the porous structure;
- c) a poly(propylenimine) (PPI) sorbent, wherein the PPI sorbent is in a plurality of pores of the porous structure, the PPI has one or both of a loading of about 10% to 75% by weight of the composite and a counterion content of less than about 0.1 mol counterion/mol amine or a combination thereof.

A method of capturing CO2, comprising:
- exposing a gas mixture to a porous structure having supported thereon at least one of:
- a) a poly(propylenimine) (PPI) sorbent, wherein the PPI sorbent is in a plurality of pores of the porous structure, wherein the PPI sorbent comprises a linear PPI, a dendritic PPI, or both the linear PPI and the dendritic PPI;
- b) a poly(propylenimine) (PPI) sorbent, wherein the PPI is physically impregnated in the porous structure and not covalently bonded to the porous structure;
- and
- c) a poly(propylenimine) (PPI) sorbent, wherein the PPI sorbent is in a plurality of pores of the porous structure, wherein the PPI has one or both of a loading of about 10% to 75% by weight of the composite and a counterion content of less than about 0.1 mol counterion/mol amine or a combination thereof;
- and
- capturing the CO2 in the structure;
- capturing in the porous structure the CO2 from the gas mixture.
