Title : Enhancement of CO2 performance with incorporation of amino functionalized filler in mixed matrix membrane
Mixed matrix membrane for gas separation is an advanced technology for the cost effective fabrication of high performing defect-free membranes. Compared to the conventional membranes, mixed matrix membrane prove to be effective for cleaner energy production, natural gas purification and CO2 capture from flue gas systems. This class of membranes, provide synergistic effect on the functional integration of organic matrix (performing within the trade-offs of Robeson’s plot) and inorganic filler materials (performing beyond the Robeson’s plot based trade-offs). The broad domain of MMM research and development devotes towards selection of appropriate materials, defect-free inexpensive fabrication techniques and characterization for simulated and real world application scenarios. The efficient large-scale uses depend comprehensively on the development of highly compatible polymer-filler interface without any defects or interfacial voids. Usually, its observed that for poor phase boundary interaction, the CO2 separation performance shows declined results. To address this issue, addition of modifying agents plays a pivotal role in improving the gas transport performance (CO2 permeability as well as CO2/N2 selectivity). A critical discussion on the fillers used and its consecutive modification has been discussed in detail in this following work. The influence of these material on the overall physicochemical property of the membrane material has been discussed in detail.
