Amine-grafted porous polymer networks were investigated for CO2 capture directly from air (400 ppm CO2, 78.96% N-2, and 21% O-2). Under these ultradilute conditions, PPN-6-CH(2)DETA has an extraordinarily high CO2 selectivity (3.6 x 10(10)) and loading capacity (1.04 mol/kg) as calculated using ideal adsorption solution theory. In addition we have shown that the material outperforms other materials based on simulated breakthrough calculations, thus showing great potential to be used in direct air capture applications.
