| Abstract |
To apply the CO2 adsorbent to the post-combustion capture process, the materials should be water-stable because of the water vapor in the flue gas. Coating the hydrophilic polymer on the surface of the metal-organic frameworks (MOFs) helps to improve stability in an environment containing moisture. We synthesized Mn-based MOFs and functionalized with diamine to enhance the CO2 adsorption ability and the synthesized MOF was coated with polydimethylsiloxane (PDMS) to form hydrophobic surface. The synthesized MOFs showed improved water stability in water vapor exposure test. These coated compounds were also confirmed by PXRD, infrared spectroscopy and gas sorption. Additionally, CO2 adsorption capacity were evaluated by thermogravimetric analysis (CO2 15% / N2 85%). Detailed synthetic scheme and specific properties will be presented in the poster. |
