Membrane technologies have been developed to suit for a wide range ofindustrial applications, and the most of them could lead to realize in very large scale. However, in general, such composite membranes can also be applied in many other ?elds. Nevertheeless, the potential of membranes for engineering of separation has by far not yet been used completely. We demonstrate a synthetic strategy toward functional, composite electrospun membrane by incorporating functional inorganic component into electrospun polymer nanofibers. Functional electrospun mats (f-ESM) could be prepared by post-modification of the surface of nanofibrous mats and application can be tailor designed accordingly. Therefore, developing a simple and versatile approach to tailor the surface properties or to introduce the desired functions into the as-fabricated electrospun nanofibrous mats is highly desirable. In this investigation, we developed new types of functional electrospun nanofibrous mats (FESNM) by intoducing inorganic functional component which has high affinity for lithium ions. The changes in the surface morphology and structural characteristics were evaluated by field emission scanning electron microscopy, Fourier transform infra red spectroscopy and thermogravimetric analysis.. The nanostructures provide high surface area for effective functionalization and our results demonstrated the high potential for efficient extraction of lithium.
