摘要： 研究了甲基丙烯酸八氟戊酯-乙烯基咪唑共聚物与钴卟啉复合膜的制备及钴卟啉与氧络合、促进输送性能.共聚物中的咪唑基与钴卟啉的第五配位点在溶液中络合,制得的复合膜具有快速和可逆的氧结合特性.温度降低,钴卟啉与氧络合的平衡常数增加;膜中的钴卟啉与氧络合平衡常数大于N,N-二甲基甲酰胺(DMF)溶液中的平衡常数.钴卟啉与氧络合和选择性地促进氧的输送使共聚物/钴卟啉复合膜的氧渗透系数和氧/氮选择系数提高.

Abstract: The membrane of poly(vinylimidazole-co-fluoroalkyl methacrylate)(FIm) complexed with meso-α,α,α,α-tetrakis(o-pivalamidophenyl)-porphyrinatocobalt(Ⅱ)(CoP) was prepared by complexing the imidazole residue of the copolymer on the fifth coordination site of CoP. Solvents had some effect on keeping CoP active during the preparation of the complexed membrane. The oxygen-binding properties and facilitated oxygen transport of the membrane were also studied. It was found that CoP fixed in the membrane had rapid and reversible oxygen-binding properties in response to the partial oxygen pressures. The oxygen-binding affinity of CoP fixed in the membrane was larger than that in the solution state. With the decrease of temperature, the oxygen-binding affinity of CoP increased. Oxygen permeation was selectively facilitated with CoP fixed in the membrane, and a high oxygen permeability [10-10 cm3(STP)·cm·cm-2·s-1·Pa-1] was observed in the FIm/CoP complexed membrane.

Key words: Poly(vinylimidazole-co-fluoroalkylmethacrylate), Cobaltporphyrin, Complexed membrane, Facilitated oxygen transport
