| Summary: | Polyvinyl chloride (PVC) and polyethyl methacrylate (PEMA) were used to prepare polymer blends for use in solid polymer electrolyte. Dynamic mechanical analysis showed that both the storage modulus (E') and the glass transition temperature (T g) of the PVC/PEMA blend are intermediate between those of the two component polymers. Scanning electron microscopy proved that addition of PEMA into PVC changed the morphology of the blends. The shifts in Fourier transform infrared bands and X-ray diffraction peaks together with the presence of a single T g suggest that the blends are partially miscible. The blend with 35 wt % PEMA seems to be the most suitable candidate for use as polymer host in polymer electrolyte, because it has the most suitable mechanical property and is the most amorphous blend system. This blend system also has the highest room temperature conductivity value of 4.74 × 10 -10 S cm -1 amongst other blend systems. © 2012 Wiley Periodicals, Inc.
