This paper proposes a novel process, SBS + SI, which integrates Solution Blow Spinning (SBS) and Solution Impregnation Method (SI), using polyamide 66 (PA66) as the carrier material and high-purity tetraethylenepentamine (TEPA) as the modifier, to fabricate nanofiber adsorption membranes with varying carrier structures and modifier component loadings. The CO2 adsorption performance and pore structure of the adsorbents were investigated using characterization techniques, such as Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), Brunauer-Emmett-Teller (BET) surface area and pore size analysis, and Fourier Transform Infrared Spectroscopy (FT-IR). The results indicate that as the mass fraction of TEPA increases, the pores in the nanofiber membranes gradually decrease, while the CO2 adsorption capacity significantly increases. The PA66 nanofiber membrane achieves peak CO2 capture performance (44.7 mg\/g at 25 \u00b0C) at 15% TEPA loading. Meanwhile, the composite nanofiber membranes also exhibit outstanding CO2\/N2 selectivity with a separation factor reaching 28. Thermal regeneration tests at 90 \u00b0C confirm the composite\u2019s outstanding cyclic stability and regenerability, demonstrating its potential for practical carbon capture applications. These findings suggest that the nanofiber adsorbents prepared by the SBS + SI process have broad application prospects in the field of CO2 capture.<\/jats:p>","DOI":"10.3390\/ma18102303","type":"journal-article","created":{"date-parts":[[2025,5,15]],"date-time":"2025-05-15T08:56:55Z","timestamp":1747299415000},"page":"2303","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Preparation of Composite Nanofiber Membranes via Solution Blow Spinning and Solution Impregnation Method for CO2 Capture"],"prefix":"10.3390","volume":"18","author":[{"given":"Kaiwen","family":"Yang","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changshun","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiguang","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuefei","family":"Fan","sequence":"additional","affiliation":[{"name":"Zhenjiang Sanwei Conveying Equipment Co., Ltd., Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"110490","DOI":"10.1016\/j.rser.2020.110490","article-title":"Post-combustion carbon capture","volume":"138","author":"Chao","year":"2021","journal-title":"Renew.
