Ion-conducting thin film polymeric electrolytes were synthesized by mixing high molecular weight Poly(ethylene oxide) (PEO), poly(methyl methacrylate) (PMMA) as a polymer matrix, Cetylpyridinium chloride (CPC) modified montmorillonite (MMT) as a filler, and with varying content of LiClO4 by solution casting technique. The thermal, morphological and rheological properties of the electrolytes were evaluated by using (Thermogravimetric / Differential Thermal Analysis (TG/DTA), Quick Thermal Conductivity Meter (QTM), Scanning Electron Microscopy (SEM), and Rheometer techniques respectively. The addition of CPC-modified clay to the polymeric electrolytes showed better dispersion at 3.5 wt. % of salt and resulted in enhanced thermal performance. The thermal conductivity of thin films was found to be very sensitive to the amount of clay addition in the system, and showed a linear decrease with the increasing clay content in the system. High MW PMMA incorporation at 50 wt. % to the composite system of PEO resulted in the agglomeration of clay particles in the composite system.
