A Novel Polymer Gel Electrolyte: Direct Polymerization of Ionic Liquid from Surface of Silica Nanoparticles
A novel polymer electrolyte is synthesized by directly grafting poly ionic liquids onto silica nanoparticles. The kinetic study of this surface-initiated polymerization has also been included. A gel-state electrolyte is formed by mixing this type of polymer/silica nanocomposite with ionic liquids under 60 degrees C, which exhibits an excellent conductivity of 0.8 mS/cm at room temperature and 14.7 mS/cm at 90 degrees C. In addition, the mechanism of gel formation has also been discussed in this article. (c) 2013 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2014, 52, 121-127
