Organic porous polymers are gaining much attention for their potential applications in gas capture and storage. On the basis of selection of appropriate monomers, purely organic rigid and contorted macromolecular structures with low skeletal density, amide-linked organic framework polymers, have been synthesized using cost-effective protocol. Polyamide chains were synthesized via low temperature condensation between 2,4,6-triamino-1,3,5-triazine and terephthaloyl chloride and isophthaloyl chloride to yield PA-1 and PA-2, respectively. The synthesized polymers were further carbonized at 600oC to fabricate nitrogen containing carbon material. These as prepared materials were subjected to analyses including FTIR, XRD, TGA, FESEM, elemental analysis, XPS, specific surface area and pore size analysis and CO2 adsorption measurements. The triazine ring with basic nitrogen atom and amide linkage in main chain are responsible for CO2 capture. |
