| 1 | PVA/PVP blend polymer matrix for hosting carriers in facilitated transport membranes: Synergistic enhancement of CO2 separation performance显示文摘CO2 separation performance in facilitated transport membranes has been reported depended not only on the CO2 carrier properties but also to a great extent on the polymeric matrix regarding the capacity of retaining water and carriers as well as the processability for coating defect-free ultra-thin films. In this study, the blends of hydrophilic polymers polyvinyl pyrrolidone(PVP) and polyvinyl alcohol(PVA) were studied to find an optimal polymer matrix to host carriers in facilitated transport membranes for enhanced CO2 separation. It is found out that the optimized blend is 50/50 PVA/PVP by weight, which shows a significant increase in the water uptake(from 63 to 84%) at equilibrium state compared to the neat PVA. Polyethyleneimine(PEI) was employed to provide sample carriers to evaluate the synergistic effect of PVA and PVP on the CO2 separation performance. A thin film composite(TFC) membrane of the optimized blend(50/50 PVA/PVP with 50 wt% PEI) was fabricated on polysulfone(PSf) porous support. The fabrication of the TFC membranes is simple and low cost, and CO2 permeance of the optimized blend membrane is nearly doubled with the CO2/N2 selectivity remained unchanged, showing great potential for industrial applications of the resulted membranes. | Ragne Marie Lilleby Helberg Zhongde Dai Luca Ansaloni Liyuan Deng | 2020 | Green Energy & Environment2020，5，1： | 5 |

| 17 | Nanocomposite membranes with high-charge and size-screened phosphorylated nanocellulose fibrils for CO_(2)separation显示文摘In this study,cellulose nanofibrils(CNF)of high charge(H-P-CNF)and screened size(H-P-CNF-S)were fabricated by increasing the charge of phosphorylated cellulose nanofibrils(P-CNFs)during the pre-treatment step of CNF production.Results show that the H-P-CNF have a significantly higher charge(3.41 mmol g^(-1))compared with P-CNF(1.86 mmol g^(-1)).Centrifugation of H-P-CNF gave a supernatant with higher charge(5.4 mmol g^(-1))and a reduced size(H-P-CNF-S).These tailored nanocelluloses were added to polyvinyl alcohol(PVA)solutions and the suspensions were successfully coated on porous polysulfone(PSf)supports to produce thin-film nanocomposite membranes.The humid mixed gas permeation tests show that CO_(2)permeability increases for membranes with the addition of H-P-CNF-S by 52%and 160%,compared with the P-CNF/PVA membrane and neat PVA membrane,respectively. | Ragne Marie Lilleby Helberg Jonathan Ø.Torstensen Zhongde Dai Saravanan Janakiram Gary Chinga-Carrasco Øyvind W.Gregersen Kristin Syverud Liyuan Deng | 2021 | Green Energy & Environment2021，6，4： | 0 |
