The authors prepared almost amorphous polyethylene oxide separation membranes through cross-linking methods, with a CO\n                    <jats:sub>2<\/jats:sub>\n                    \/H\n                    <jats:sub>2<\/jats:sub>\n                    separation coefficient of 7.9. However, there is still the drawback of low CO\n                    <jats:sub>2<\/jats:sub>\n                    permeability. To improve the performance of the cross-linked membranes, this paper utilized the swelling property of the cross-linked membranes and immersed them with different end groups of PEG aqueous solutions. The effects of different end groups on the gas separation performance of the cross-linked membranes were investigated. The results showed that after being impregnated with different end group PEG, the gas permeabilities of the cross-linked membranes increased. When using a polyethylene glycol with a molecular weight of 250\u2009g\/mol for impregnation, a 47.0wt.% increase in weight was observed, and the gas permeability and CO\n                    <jats:sub>2<\/jats:sub>\n                    \/H\n                    <jats:sub>2<\/jats:sub>\n                    separation coefficient of the cross-linked membranes increased significantly. The CO\n                    <jats:sub>2<\/jats:sub>\n                    permeability increased from 170 Barrer of the original membrane to 1457 Barrer, and the separation coefficient of H\n                    <jats:sub>2<\/jats:sub>\n                    increased from 7.9 to 13.\n                  <\/jats:p>","DOI":"10.1371\/journal.pone.0346667","type":"journal-article","created":{"date-parts":[[2026,4,10]],"date-time":"2026-04-10T17:38:35Z","timestamp":1775842715000},"page":"e0346667","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effect of impregnation with polyethylene glycols (PEGs) of different end groups on gas separation performance of cross-linked polyethylene oxide (PEO) membranes"],"prefix":"10.1371","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-3261-3209","authenticated-orcid":true,"given":"Shanshan","family":"Ji","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu","family":"Guan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengyang","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuai","family":"Quan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuewei","family":"Dong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianzhi","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fandi","family":"Meng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhicheng","family":"Tian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2026,4,10]]},"reference":[{"key":"pone.0346667.ref001","volume-title":"Climate Change 2023: Synthesis Report.
