We report on the application of a sorbent design principle to the encapsulation of polyethylenimine (PEI) in silica “nanobubbles” as CO2 capture material.   High sorption capacities combined with exceptionally fast sorption kinetics for these "PEI nanobubbles" suggest these materials constitute a very promising class of sorbents for carbon capture.
