| Abstract |
Moisture sensitivity of metal-organic frameworks (MOFs) is an important issue in carbon capture applications. We synthesized amine-functionalized Mn-MOF and coated the surface of the MOF with polydimethylsiloxane (PDMS) to convert the surface from hydrophilic to hydrophobic. The synthesized MOFs showed improved water stability and CO2 adsorption capacity after water vapor exposed. These coated compounds were confirmed by powder X-ray diffraction, infrared spectroscopy and sorption. Additionally, carbon dioxide adsorption capacity were evaluated by thermogravimetric analysis (CO2 15% / N2 85%). Detailed synthetic scheme and specific properties will be presented in the poster. |
