Abstract：

To improve the permeance and selectivity of CO2 separation membrane at high pressure, polyvinylamine (PVAm)-3-methoxyl benzyl amine coating solution was prepared by mixing PVAmaqueous solution with 3-methoxy benzyl amine. The PVAm-3-methoxyl benzyl amine/polysulfone (PSf) fixed carrier composite membrane was prepared by coating PVAm-3-methoxyl benzyl amine solution on the PSf membrane. The ATR-FTIR spectra of the membrane showed that the intermolecular hydrogen bonds are formed between the primary amine groups of 3-methoxyl benzyl amine and primary amine or amide groups in PVAm. CO2 permeance and CO2/N2 selectivity of the PVAm-3-methoxyl benzyl amine/PSf and PVAm/PSf membranes were tested by using CO2/N2 mixed gas (20/80 by volume). The PVAm-3-methoxyl benzyl amine/PSf membrane displays high CO2/N2 separation performance, especially at high pressure, which is attributed to three structural characteristics of the membrane. Firstly, the membrane was densified due to the intermolecular hydrogen bonds formed between PVAm and 3-methoxy benzyl amine. Secondly, the amine group concentration of the membrane was increased. Thirdly, the ether oxygen groups were introduced into the membrane.
