摘要：
A sandwich-like composite membrane was prepared with cellulose electrospun membrane as intermediate layer, linear poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) as membrane substrate, poly(ethylene glycol) methyl ether methacrylate (PEGMEMA) and methyl methacrylate (MMA) as monomer, trimethylolpropane triacrylate (TMPTA) as crosslinking agent. The experimental results illustrate t hat the ion conductivity and mechanical strength of the modified membrane are significantly improved, which reach 1.8 mS/cm and 12.5 MPa, respectively. The modified membrane also has a good dimensional stability at 180℃ compared with commercial PE membranes. The dcell assembled by composite membranes shows a favorable cycle performance and C-rate capability, with the discharge capacity of 137 m A•h/g under the 0.5 C/0.5 C battery test. © 2019, Editorial Board of Polymer Materials Science & Engineering.
