By combining the highly porous and contorted structure of PIM (polymers with intrinsic microporosity) and high thermomechanical properties of PI (polyimide), the membranes obtained from these random copolymers [(PIM-PI)-(6FDA-durene-PI)] showed high CO2 permeability (&gt;1047 Barrer) with moderate CO2\/N2 (&gt; 16.5) and CO2\/CH4 (&gt; 18) selectivity, together with excellent thermal and mechanical properties. The membranes prepared from three different compositions of two comonomers (1:4, 1:6 and 1:10 of x:y), all showed similar morphological and physical properties, and gas separating performance, indicating ease of synthesis and practicability for production in large scale. The gas separation performance of these membranes at various pressure ranges (100\u20131500 torr) was also investigated.<\/jats:p>","DOI":"10.3390\/membranes9090113","type":"journal-article","created":{"date-parts":[[2019,9,2]],"date-time":"2019-09-02T03:16:12Z","timestamp":1567394172000},"page":"113","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["A Facile Synthesis of (PIM-Polyimide)-(6FDA-Durene-Polyimide) Copolymer as Novel Polymer Membranes for CO2 Separation"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1363-8527","authenticated-orcid":false,"given":"Iqubal","family":"Hossain","sequence":"first","affiliation":[{"name":"Organic Material Synthesis Laboratory, Department of Chemistry, Incheon National University, Incheon 22012, Korea"},{"name":"Research Institute of Basic Sciences, Incheon National University, Incheon 22012, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0301-6812","authenticated-orcid":false,"given":"Abu","family":"Al Munsur","sequence":"additional","affiliation":[{"name":"Organic Material Synthesis Laboratory, Department of Chemistry, Incheon National University, Incheon 22012, Korea"},{"name":"Research Institute of Basic Sciences, Incheon National University, Incheon 22012, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1654-3785","authenticated-orcid":false,"given":"Tae-Hyun","family":"Kim","sequence":"additional","affiliation":[{"name":"Organic Material Synthesis Laboratory, Department of Chemistry, Incheon National University, Incheon 22012, Korea"},{"name":"Research Institute of Basic Sciences, Incheon National University, Incheon 22012, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,31]]},"reference":[{"key":"ref_1","first-page":"4467","article-title":"A Technical, Economic, and Environmental Assessment of Amine-Based CO2 Capture Technology for Power Plant Greenhouse Gas Control","volume":"412","author":"Rao","year":"2002","journal-title":"Energy Environ.
