The current climate change effects motivate an urgent need for new and sustainable materials to capture CO2. Porous materials are particularly interesting for processes that take place near atmospheric pressure. However, materials design should not only consider the morphology, but also the chemical identity of the CO2 sorbent to enhance the affinity towards CO2. Poly(ionic liquid)s (PILs) can enhance CO2 sorption capacity, but tailoring the porosity is still a challenge. Aerogel\u2019s properties grant production strategies that ensure a porosity control. In this work, we joined both worlds, PILs and aerogels, to produce a sustainable CO2 sorbent. PIL-chitosan aerogels (AEROPILs) in the form of beads were successfully obtained with high porosity (94.6\u201397.0%) and surface areas (270\u2013744 m2\/g). AEROPILs were applied for the first time as CO2 sorbents. The combination of PILs with chitosan aerogels generally increased the CO2 sorption capability of these materials, being the maximum CO2 capture capacity obtained (0.70 mmol g\u22121, at 25 \u00b0C and 1 bar) for the CHT:P[DADMA]Cl30%AEROPIL.<\/jats:p>","DOI":"10.3390\/ijms23010200","type":"journal-article","created":{"date-parts":[[2021,12,27]],"date-time":"2021-12-27T01:00:54Z","timestamp":1640566854000},"page":"200","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["The AEROPILs Generation: Novel Poly(Ionic Liquid)-Based Aerogels for CO2 Capture"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5225-8714","authenticated-orcid":false,"given":"Raquel V.","family":"Barrulas","sequence":"first","affiliation":[{"name":"i3N|Cenimat, Department of Materials Science (DCM), NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5477-1762","authenticated-orcid":false,"given":"Clara","family":"L\u00f3pez-Iglesias","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Pharmacy and Pharmaceutical Technology, I+D Farma Group (GI-1645), Faculty of Pharmacy and Health Research Institute of Santiago de Compostela (IDIS), Universidade de Santiago de Compostela, E-15782 Santiago de Compostela, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3080-3627","authenticated-orcid":false,"given":"Marcileia","family":"Zanatta","sequence":"additional","affiliation":[{"name":"i3N|Cenimat, Department of Materials Science (DCM), NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"given":"Teresa","family":"Casimiro","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE, Chemistry Department, NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]},{"given":"Gonzalo","family":"M\u00e1rmol","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE, Instituto de Investiga\u00e7\u00e3o e Forma\u00e7\u00e3o Avan\u00e7ada, Departamento de Qu\u00edmica e Bioqu\u00edmica, Escola de Ci\u00eancias e Tecnologia, Col\u00e9gio Lu\u00eds Ant\u00f3nio Verney, Universidade de \u00c9vora, 7000-671 Evora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4856-5150","authenticated-orcid":false,"given":"Manuela Ribeiro","family":"Carrott","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE, Instituto de Investiga\u00e7\u00e3o e Forma\u00e7\u00e3o Avan\u00e7ada, Departamento de Qu\u00edmica e Bioqu\u00edmica, Escola de Ci\u00eancias e Tecnologia, Col\u00e9gio Lu\u00eds Ant\u00f3nio Verney, Universidade de \u00c9vora, 7000-671 Evora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9542-3679","authenticated-orcid":false,"given":"Carlos A.","family":"Garc\u00eda-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Pharmacy and Pharmaceutical Technology, I+D Farma Group (GI-1645), Faculty of Pharmacy and Health Research Institute of Santiago de Compostela (IDIS), Universidade de Santiago de Compostela, E-15782 Santiago de Compostela, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0890-6133","authenticated-orcid":false,"given":"Marta C.","family":"Corvo","sequence":"additional","affiliation":[{"name":"i3N|Cenimat, Department of Materials Science (DCM), NOVA School of Science and Technology, NOVA University Lisbon, 2829-516 Caparica, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"69","DOI":"10.1016\/j.jcou.2013.03.002","article-title":"Opportunities and challenges in carbon dioxide capture","volume":"1","author":"Spigarelli","year":"2013","journal-title":"J.
