渗透汽化技术因其高效和环保性引起了广泛关注,尤其在液体分离领域.高选择性渗透膜材料设计的主要目标是提升膜的选择性、渗透性和稳定性.混合基质膜将无机填料均匀分散于聚合物基质中,形成有机-无机杂化复合材料,以增加制备高性能渗透汽化膜的可操作性和灵活性.具有层状结构的水滑石由于连续片层可以减少扩散路径,在聚合物基体内可能构建出分子筛通道,从而提高膜的分离效果.
Progress in Pervaporation Properties of Tenary Hydrotalcite
Pervaporation membrane,which exhibits high separation efficiency and environmental friendliness,has emerged as a captivating technology for liquid mixture separation.The primary focus in designing membranes with highly selective permeability lies in enhancing selectivity,permeability,and stability.By incorporating inorganic fillers into the polymer matrix,hybrid matrix membranes(MMMs)offer a novel approach to achieving operational flexibility and high-performance membranes.2D layer double hydroxide nanoplates present promising transport channels within the matrix for efficient molecular separation due to their continuous planar surfaces and low mass transport resistance.
