Effects of composition and structure on the ionic conductivity of latex polymer electrolyte

Abstract

A series of poly(ethyl acrylate)/lithium salts were prepared. The ionic conductivity of latex films was compared with films prepared by solution polymerisation. By changing the composition of the latex and the lithium salt, we studied the influence of the latex surface composition, particle size, the lithium salt and its concentration on the conductivity of polymer electrolyte latex films. The results show that surface layer transport of ions plays an important role in increasing the ionic conductivity of polymer electrolytes.
