A Facilitate Process to Prepare Hydrophilic Ionic Liquid Monomers Free Of Halide Impurity and Their Electrochemical Properties

摘要

A facilitate and halide-free process to prepare ionic liquid monomers with various anions wasdeveloped with dialkylsulphate as the alkylating agent. The results imply that the process was efficientto prepare ionic liquid monomers for poly ionic liquids which have been proposed as promisingalternative polymer electrolyte for various electric devices such as fuel cell, Li ion battery.Furthermore, ionic conductivity of both the ionic liquid monomers was measured as a function oftemperature. Electrochemical window was measured with acyclic voltammogram (CV) method. Theresults show that it is a facilitate and versatile method to prepare imidazolium type ionic liquidmonomers without halide impurity.
