Covalent organic framework(COF) membranes have exhibited great potential to become the next-generation membranes for efficient separations due to the diverse structures, ordered framework pores, tunable functionality and excellent stability. This review presents the microstructure manipulation strategies for separation performance enhancement of COF membranes in recent years. Based on the three mechanisms of molecular sieving, surface diffusion, and facilitated transport, the structural modulation methods to enhance the selectivity of COF membranes are analyzed in detail. Next, strategies of realizing ultrashort mass transfer pathways and ultralow mass transfer resistance for the permeability enhancement are elaborated. Furthermore, the framework stability in COFs, interlayer stability between COF nanosheets and interfacial stability between COF layer and substrate are discussed. Finally, we discuss the existing challenges and perspectives on the future development of COF membranes, targeting at identifying the most promising strategies and directions for the engineering of COF membranes.

为茶渣废弃资源的科学合理利用提供参考,以红芯娃娃菜品种为试验材料,采用盆栽试验研究茶渣与红土不同配比基质栽培娃娃菜对其幼苗生长及品质的影响。结果表明:茶渣与红土不同配比基质对娃娃菜幼苗生长及品质的影响存在一定差异。随着红土配比增加或茶渣配比减少,娃娃菜幼苗的单株叶片数、茎粗、单株重及根重呈不断增加趋势,株高和根长则呈逐渐下降趋势,并以茶渣∶红土为1∶3基质栽培娃娃菜的幼苗综合素质最好,茶渣∶红土为1∶2基质其次,而纯茶渣基质则不利娃娃菜生长。娃娃菜幼苗叶片的叶绿素、可溶性糖和Vc含量随茶渣配比减少分别呈逐渐增加、不断减少和先减少后增加趋势。因此,合适的茶渣与红土配比可促进娃娃菜幼苗生长,并提高其品质。
