  • ion conducting polymers have been extensively investigated because of their potential application as an electrolyte in solid state batteries [1]. Among the polymer electrolytes, solid polymer electrolytes (SPEs) composed of ion conducting polymer and alkali metal salt have many advantages such as high ionic conductivity, high energy density and light weight. This made them suitable replacement for liquid electrolytes. (omitted)

  • We report a microcapsule-based electronic ink display technique, containing hollow titania particles which were prepared via a complex coacervation method using gelatin and gum arabic. In order to reduce density mismatch between nanoparticels and dielectric medium, hollow titania particles were introduced. Microcapsules were then prepared using gelatin to improve the elasticity of the microcapsule wall and their electrophoretic characteristics were $investigated^1$
