Synthesis of microporous membranes and films on various substrates by novel electrospinning method

The introduction of electrospinning technique in synthesis of supported microporous membranes and films opens bright prospects for mass production and practical applications. This novel and promising strategy has wide suitable range for various substrates with the possibility of large-area processing. We successfully synthesized several kinds of microporous materials into high quality membranes and films on different shaped supports by this method, such as zeolite NaA and pure-silica-zeolite Beta membranes on porous Al2O3 tube, zeolite NaY membrane on stainless steel net and a metal-organic framework Eu(BTC)(H2O)·DMF (JUC-32) film on porous silica disc. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used as characterization means. The results verified the effectiveness of this new approach in fabrication of membranes and films.
