Abstract
Methods are provided for synthesizing novel types of self-assembled siloxanes, such as polysiloxanes, with a sufficiently high density of amine functional groups to be useful for CO2 capture and release processes. Additionally, it has been unexpectedly found that some self-assembled polysiloxanes can be used for high temperature adsorption of CO2.
