Polyethylene terephthalate(PET)@CuBTC composite fiber membranes are prepared through a simple,low-cost layer-by-layer growth method based on CuBTC,which is made via aqueous phase synthesis method.Surface morphology of PET fibers produced is successfully controlled through two steps of electrospinning and post-treatment.The growth size and morphology of CuBTC is controlled through adjusting the growth cycle,and PET@CuBTC composite fiber membranes with uniform fiber diameter,high specific surface area,and dense,firm and moderate size of backbone crystal layer are prepared.Results show that this scheme effectively solves the problem that the powder form of MOF limits its application,and demonstrates the potential application value of PET@CuBTC composite fiber membranes in high efficiency filtration and bacterial inhibition.
