Keywords： PVdF-HFP

Polyvinylidene fluoride-hexafluoropropylene(PVdF-HFP)/clay nanocomposite membranes were prepared by phase inversion method through controlling retention time to apply for a lithium ion secondary batteries.Increased membrane porosity with macrovoids was observed at increasing retention time.Partially intercalated structures of PVdF-HFP/clay nanocomposite membranes were confirmed by X-ray diffraction(XRD)analysis.PVdF-HFP membranes containing various kind of clay showed the increase of membrane modulus compared to the pristine PVdF-HFP membrane.
