Polyether block amide (PEBA) polymeric layers were prepared on polysulfone (PSf) supports via dip coating. The effects of the coating speed and the solution concentration on the membrane performance were studied. The membranes were characterized by scanning electron microscopy, Fourier transform infrared spectra, and gas permeation. The coating speed was adjusted in the range of 0.32–0.48 cm s−1 at a solution concentration of 3 wt % to obtain suitable membranes so that the CO2 permeance and the CO2/N2 selectivity increased by more than three and ten times, respectively, compared to other speed ranges. Statistical analysis also showed that the effect of the interaction between solution concentration and coating speed is more considerable than the separate effects of both factors.

用于二氧化碳分离的PEBA / PSf多层复合膜：浸涂参数的影响
通过浸涂在聚砜（PSf）载体上制备聚醚嵌段酰胺（PEBA）聚合物层。研究了涂布速度和溶液浓度对膜性能的影响。通过扫描电子显微镜，傅立叶变换红外光谱和气体渗透来表征膜。在3 wt％的溶液浓度下，将涂布速度调节在0.32-0.48 cm s -1的范围内，以获得合适的膜，以使CO 2透过率和CO 2 / N 2与其他速度范围相比，选择性分别提高了三倍和十倍以上。统计分析还表明，溶液浓度和涂布速度之间相互作用的影响比两个因素的单独影响更为显着。
