Structural, thermal, and electrical studies of sodium iodide (NaI)-doped hydroxypropyl methylcellulose (HPMC) polymer electrolyte films

Methylcellulose-Sodium Iodide (MC-NaI) solid polymer electrolyte was prepared using solution cast technique and the conductivity and permittivity characteristics of the material were studied. FTIR studies confirmed that NaI plays a role as the conducting ions without altering the molecular structure of the polymer. Using Electrical Impedance Spectroscopy technique, it was found that the conductivity of MC-NaI polymer matrix to be the highest at 40 wt% NaI (2.70x10-5 S/cm). Conductivity of MC-NaI also increases with temperature, but decreases as temperature exceeds 333K. Dielectric studies of the material also confirm these findings, where it was found that dielectric constant and dielectric loss to be the highestat 40 wt% NaI at low frequency.

Poly(vinylpyrrolidone) (PVP) complexed with sodium iodide (NaI) is synthesized to investigate the ionic conductivity of alkaline-based polymer electrolytes. In this article, we report the modification of electrical properties of a new ion-conducting polymer electrolyte, namely, PVP complexed with NaI. Modification of polymer electrolyte was carried out before and after the exposure of films by bombarding them at different fluences with respect to Li3+ ion beam at 60 MeV. The preparation and detailed characterization of PVP:NaI is being reported. Further, a correlation with conductivity and dielectric constant has also been established. The modulation in the conductivity is explained in terms of number of charge carriers ( n) and its mobility ( μ), which confirms the behavior of the polymer electrolyte as an alternative strategy to improve the conductivity.
