Abstract

The novel mixed-matrix membrane (MMMs) by incorporating covalently amino groups grafted nano-silica (Amino-NP) into an eco-friendly, organic solvent-free waterborne polyurethane (OSF-WPU) matrix for the separation application of CO₂/N₂. This investigation focused on the gas permeance and separation performance of the MMMs. The optimized CO₂/N₂ separation factor reached $8.21 \pm 0.47$ , with a CO₂ permeance of $16.72 \pm 1.02$ GPU under conditions of 1.0 bar and 25^∘C in a wet mixed-gas state. Incorporating even a tiny amount of Amino-NP efficiently enhanced CO₂ permeability and CO₂/N₂ selectivity. OSF-WPU/Amino-NP MMMs demonstrated superior performance, emphasize their potential for stable long-term operation in practical CO₂ separation applications.

水性聚氨酯与氨基接枝二氧化硅的无有机溶剂原位聚合，用于二氧化碳分离

将共价氨基接枝纳米二氧化硅（Amino-NP）加入环保型无有机溶剂水性聚氨酯（OSF-WPU）基质中，制成新型混合基质膜（MMMs），用于分离 CO2/N2。这项研究的重点是 MMM 的气体渗透性和分离性能。在 1.0 巴和 25∘C 条件下，湿混合气体状态下的 CO2/N2 分离系数达到 8.21±0.47，CO2 渗透率为 16.72±1.02 GPU。即使加入极少量的 Amino-NP 也能有效提高二氧化碳渗透率和 CO2/N2 选择性。OSF-WPU/Amino-NP MMMs 表现出卓越的性能，强调了它们在实际二氧化碳分离应用中长期稳定运行的潜力。
