英文摘要: The condensation of aromatic and brominated monomers using the solvent knitting strategy has produced new porous polyphenylenes with high specific surfaces areas (935-1950 m 2 g -1 ) and high bromine content (10-22 %). These bromine-polymers have been functionalized in a single step by reaction with TREN or TEPA alkylamines, studying their effect on the CO 2 adsorption properties. Pure CO 2 analyses show a maximum uptake of 1.03 and 1.54 mmol CO 2 /g for 2 Ph-TEPA and 5 Ph-TEPA respectively at 30 °C and atmospheric pressure. Resulting materials allow low heating cost during regeneration, and high stability after CO 2 adsorption-desorption cycles, making these materials more easily recyclable than other TEPA-impregnated adsorbents. © 2019 Elsevier Ltd.
