Structural and Ionic Conductivity Properties of Gamma Irradiated HPMC Polymer Electrolyte Films
Journal Title: Journal of Advanced Research in Manufacturing, Material Science & Metallurgical Engineering - Year 2018, Vol 5, Issue 1
Abstract
A solid biopolymer electrolytes (BEs) based on hydroxypropyl methylcellulose (HPMC) doped with different concentrations of cadmium chloride (CdCl2 ) and ceric ammonium nitrate (NH4 ) 2 Ce(NO3 ) 6 (CAN) were prepared by solution cast method. Different techniques have been employed to investigate the effects of structural and electrical conductivity behavior of these polymer electrolyte films upon gamma irradiation with different dose. Results based on x-ray diffraction revealed that, the amorphous domains of HPMC polymer matrix was increased with increase in the salt concentration and with the gamma dose. The percentage of crystallinity is found to be high in pristine un-irradiated HPMC films. The temperature-dependent of HPMC based BEs system conductivity data obeys Arrhenius relationship. Conductivity enhancement in these BEs is caused not only by the increase in the concentration of dopant salt but also by the increase in mobility and diffusion coefficient of ions and with increasing gamma dose.
