Poly(acrylonitrile)-montmorillonite nanocomposites Effects of the intercalation of the filler on the conductivity of composite polymer electrolytes
Author
Abstract
In this work, a series of composite polymer electrolytes (CPEs) basically constituted by polyacrylonitrile
(PAN) and a clay, montmorillonite (Bentonite), as filler have been developed, in which the clay in its
lithiated form was used both as prepared and intercalated with PAN .The effect of these two forms of
nanoceramic active filler on the properties of the CPEs was analyzed. Results show that the ionic conductivity
of the CPEs using as filler Bentonite-Li+-polyacrylonitrile nanocomposite is about one order of
magnitude higher than that using Bentonite-Li+ under the same conditions. The effect of the concentration
of the filler on the conductivity of the products is discussed.
