Pervaporation is a molecular separation membrane technology for selective permeation of water or organic compounds from organic-water mixtures or organic-organic mixtures. The pervaporation process is controlled by thermodynamic partitioning and kinetic mobility of molecules in the membrane. The chemical property and morphology of membrane materials can be engineered to tailor the complementary sorption and diffusion coefficient and selectivity, and thus the permeability (or flux) and selectivity (or separation factor). In this review, we highlight the latest progresses of pervaporation membrane materials, including pure polymeric membranes and inorganic membranes, as well as mixed-matrix membranes and emerging two-dimensional-material membranes. Challenges and future opportunities in materials design, fabrication and structure-performance relationship are identified to develop next-generation pervaporation membranes with enhanced separation efficiency.

渗透蒸发膜材料:近期趋势与展望
渗透蒸发是一种分子分离膜技术,用于从有机-水混合物或有机-有机混合物中选择性渗透水或有机化合物。渗透蒸发过程受膜中分子的热力学分配和动力学迁移率控制。可以设计膜材料的化学性质和形态,以定制互补的吸附和扩散系数和选择性,从而调整渗透性(或通量)和选择性(或分离因子)。在这篇综述中,我们重点介绍了渗透蒸发膜材料的最新进展,包括纯聚合物膜和无机膜,以及混合基质膜和新兴的二维材料膜。材料设计的挑战和未来机遇,
