摘要：

A non-solvent induced phase separation (NIPS) process was used to prepare a new kind of porous nanocomposite polymer electrolyte using glycerol as non-solvent for poly(vinylidene difluoride-co-hexafluoropropylene) copolymer. TiO2 nanoparticles were incorporated by in situ hydrolysis of Ti(OC4H9)(4) and dispersed uniformly in the polymer matrix. They affected the porous structure of the obtained nanocomposite polymer membranes (NCPMs). When the amount of TiO2 arrived at 7.6 wt.%, the NCPM reached the maximum porosity of 70.5%. The resulting nanocomposite polymer electrolyte (NCPE) presents an ionic conductivity of up to 1.98 x 10(-3) S . cm(-1) at room temperature and an apparent activation energy for ion transport of 13.32 kJ . mol(-1), suggesting its promising application in lithium ion batteries.
