The ZSM-5/poly (ether-block-amide) (PEBA)/polyethersulfone (PES) dual layer mixed matrix membranes (MMMs) were prepared for pervaporation (PV) separation of ethyl acetate (EAc) from aqueous solutions. The ZSM-5 zeolite nanoparticles were synthesized by the conventional hydrothermal method and characterized using the XRD, XRF and FESEM analysis. The effect of top layer thickness, PEBA concentration, zeolite loading concentration, feed concentration and temperature on the separation performance of the prepared membranes was investigated. The FTIR, SEM, contact angle and swelling tests were used to characterize the fabricated MMMs. The results indicated that loading ZSM-5 zeolite nanoparticles into the PEBA matrix had a significant influence on the separation performance of the prepared membranes. The ZSM-5/PEBA/PES membrane containing 7.5 wt% ZSM-5 with a top layer thickness of 20 μm, showed the highest separation factor. The total flux was decreased by loading ZSM-5 into the membranes up to 7.5 wt% and further enhancement in the zeolite loading content resulted in increasing the total permeation flux. The best separation factor and total flux of the ZSM-5/PEBA/PES-07.5 membrane were found to be 108.52 and 1895 g m⁻²h⁻¹, respectively for a feed concentration of 5 wt% EAc and temperature of 50 °C.

制备ZSM-5 /聚（醚嵌段酰胺）（PEBA）/聚醚砜（PES）双层混合基质膜（MMM），用于从水溶液中进行乙酸乙酯（EAc）的全蒸发（PV）分离。通过常规水热法合成ZSM-5沸石纳米颗粒，并使用XRD，XRF和FESEM分析对其进行表征。研究了顶层厚度，PEBA浓度，沸石负载浓度，进料浓度和温度对所制备膜的分离性能的影响。使用FTIR，SEM，接触角和溶胀测试来表征制造的MMM。结果表明，将ZSM-5沸石纳米颗粒加载到PEBA基质中对制备的膜的分离性能有重大影响。ZSM-5 / PEBA / PES膜含7。顶层厚度为20μm的5 wt％ZSM-5显示出最高的分离系数。通过将ZSM-5加载到膜中至多7.5 wt％，总通量得以减少，并且沸石负载量的进一步增加导致总渗透通量的增加。ZSM-5 / PEBA / PES-07.5膜的最佳分离系数和总通量分别为108.52和1895 g m进料浓度为5 wt％EAc和温度为50°C时分别为^-2 h ^-1。
