A solid sorbent for the capture and the transport of carbon dioxide gas
is provided having at least one first layer of a positively charged
material that is polyethylenimine or poly(allylamine hydrochloride),
that captures at least a portion of the gas, and at least one second
layer of a negatively charged material that is polystyrenesulfonate or
poly(acryclic acid), that transports the gas, wherein the second layer
of material is in juxtaposition to, attached to, or crosslinked with the
first layer for forming at least one bilayer, and a solid substrate
support having a porous surface, wherein one or more of the bilayers
is/are deposited on the surface of and/or within the solid substrate. A
method of preparing and using the solid sorbent is provided.
