Abstract Urea-based organic molecular networks were synthesized by using cross-linking polymerization of tetrakis (4-aminophenyl) methane and hexamethylene diisocyanate. This study shows that crosslinked urea-network polymer(UN) can be molded into the desired shape with a various length scale of pore diameter. UN was thermally treated at 250~380℃ for thermal rearrange reaction. Rearranged urea-network polymer(RUN) contains a higher volume of micropore and surface area than UN. The resultant hierarchical porous material has excellent carbon dioxide adsorption capacity and selectivity. Furthermore, we are going to discuss how melamine added copolymer affects to thermal treatment condition and carbon dioxide adsorption selectivity.
