The poly (vinylidene fluoride)/poly (methyl methacrylate)(PVDF/PMMA) composite fibrous membranes with different blend ratio for use as separator of lithium-ion batteries have been developed by electrospinning technique. The surface morphology and crystal structure of electrospun PVDF/PMMA composite fibrous membranes are characterized using scanning electron microscopy (SEM), attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy and differential scanning calorimetry (DSC).The results indicated that the addition of PMMA into PVDF increased the fiber diameter, decreased the crystalline of electrospun composite fibrous membranes and the good molecular level interaction between these two polymers were obtained. Meanwhile,electrospun PVDF/PMMA (90/10) composite fibrous membranes exhibited the highest ionic conductivity of 2.54×10-3S/cm at room temperature with electrochemical stability of up to 5.0V.

In the present work, ZIF-8/6FDA-durene mixed matrix membranes (MMMs) were synthesized and characterized. ZIF-8 nanocrystals, which were used as the inorganic filler, were synthesized using rapid room-temperature synthesis method whereas 6FDA-durene polyimide was synthesized by polycondensation method followed by chemical imidization. Pure and 6FDA-durene membranes loaded with 5 wt%, 10 wt% and 15 wt% of ZIF-8 were fabricated. The structural properties and morphology of the resultant membranes were characterized by using X-ray Diffraction (XRD) and Field emission scanning electron microscope (FESEM) . The EDX images showed that ZIF-8 particles agglomerated in the polymer matrix. However, no phase separation was observed for all resultant MMMs.
