Fabrication,thermal,morphological and rheological studies on novel organic-inorganic hybrid composites of cetylpyridinium chloride-modified montmorillonite incorporated PEO/PMMA blend

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. © 2016,chemical society of pakistan. all rights reserved.
