In this study, sodium alginate (SA)-perfluorinated sulfonic acid (PFSA)/ceramic hybrid membranes were successfully prepared by dip-coating method. The contorted rigid structure of PFSA immobilized the loose structure of SA as well as improved the interconnectivity so as to demonstrated high separation factors. Meanwhile, the ion clusters formed by SO₃H groups of PFSA possessed high affinity for water, resulting in high water flux. The viscosity of blend solution, structures and properties of the hybrid membranes were investigated by viscometry, Fourier transform infrared (FTIR), scanning electron microscopy (SEM), water contact angle meter and pervaporation dehydration. The effects of SA-PFSA ratio, PFSA content, feed composition and temperature on the separation performances of the hybrid membranes were investigated. The hybrid membrane fabricated by 2.0 wt% SA and 2.0 wt% PFSA demonstrated a high flux of 1155 g m⁻² h⁻¹ coupled with separation factor of 1149 by dehydration of 15 wt% water content ethanol-water mixture at 75 °C, reflecting superior pervaporation processing capacity.

本研究通过浸涂法成功制备了藻酸钠（SA）-全氟磺酸（PFSA）/陶瓷杂化膜。PFSA扭曲的刚性结构固定了SA的松散结构，并改善了互连性，从而显示出较高的分离因子。同时，SO ₃形成的离子簇PFSA的H基团对水具有高亲和力，因此水通量较高。通过粘度测定，傅里叶变换红外光谱（FTIR），扫描电子显微镜（SEM），水接触角仪和全蒸发脱水法研究了共混溶液的粘度，杂化膜的结构和性能。研究了SA-PFSA比，PFSA含量，进料组成和温度对杂化膜分离性能的影响。由2.0 wt％的SA和2.0 wt％的PFSA制成的杂化膜通过在75°C下脱水15 wt％的乙醇-水混合物，表现出1155 g m ^-2  h ^-1的高通量和1149的分离系数，这反映了优异的全蒸发处理能力。
