X-Ray Diffraction and Infrared Studies on Plasticized Cellulose Acetate Complexed with Ammonium Iodide for Solid Polymer Electrolyte

Gel polymer electrolyte films based on cellulose acetate (CA) complexed with ammonium iodide (NH4I), and ethylene carbonate (EC) was prepared by the solution cast technique. The conductivity increases to 10-4 Scm-1 upon the addition of salt. The incorporation of EC and to the salted polymer enhances the conductivity significantly 10-3 Scm-1. The complexation of doping materials with polymer was confirmed by X-ray diffraction and infrared studies. The present of ethylene carbonate (EC) as plasticizer did not disturbed the complexation between polymer and salt that has been confirm by FTIR. XRD studies further confirmed that all sample prepared are crystalline. This result affirmed that there were no complexations occur between plasticizer in the CA-NH4I polymer system.
