Abstract:

High stable metal-organic coordination polymer membrane was prepared by a seeding-second growth method at solvothermal condition on porous silica substrate. The morphology, structure and properties of the synthesized membrane were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), single gas permeation test and separation test of xylene mixture. The pervaporation process gave the result that this porous membrane exhibited separation performance for xylene mixture by selective adsorption. Furthermore, the thermal stability and mechanical resistence of membrane were proved by heating, ultrasonic treatment and repeated separation test.

Key words: Metal-organic coordination polymer, Separation membrane, Xylene isomers, High stability
