Main project: Rational Design of Metal-Organic Frameworks/Covalent Organic Frameworks Hybrid Membranes for Pervaporation
Funding: CSC
Supervisor(s): Patricia Luis Alconero

MMMs have become one of the research hotspots in the field of separation membranes in recent years.In MMMs, the poor compatibility between fillers and organic polymers makes the membrane surface prone to defects, which leads to the decline of separation and stability of the membrane. Therefore, improving the compatibility between hybrid particles and polymers becomes an urgent problem to be solved.MOFs and COFs have the advantages of adjustable pore size, high specific
surface area, and organic components in the framework structure, which enhances compatibility with polymers and reduces defects.The super high specific surface area and selective adsorption characteristics of MOFs and COFs materials enable MOFs hybrid membranes and COFs hybrid membranes to simultaneously increase separation factor and permeation flux, breaking the "trade-off" phenomenon.
In this study, metal-organic framework complexes (MOFs) and covalent organic framework materials (COFs) will be used as hybrid particles.Hybrid membranes will be prepared by impregnation method and applied to the separation of organics/water.The separation performance of the pervaporation membrane will be improved by utilizing the characteristics of high specific surface area and selective adsorption of MOFs and COFs particles.The morphology and surface characteristics of the hybrid membranes under different membrane formation conditions will be studied by means of XRD, SEM, EDX, FTIR, CA, AFM, etc. And the effects of membrane formation factors and operating conditions on the properties of the separation
membranes will be investigated
