Preparation of PVdF-based electrospun membranes and their application as separators

摘要

A one-step method preparing of poly(vinylidene fluoride)-based electrospun membranes (PEMs) containing TiO₂ has been developed. The effect of TiO₂ on the morphology, degree of crystallization and electrochemical behavior of PEMs was investigated by scanning electron microscopy (SEM), atomic force microscopy (AFM), differential scanning calorimetry (DSC) and electrochemical measurements. The PEMs containing TiO₂ show improved ionic conductivity and cycling performance compared with pure PEMs.
