“…2. Table 1 shows the vibrational assignments of Pure PVAc, PMMA, and PC [6][7][8][9]. The vibrational peaks at 1,410 and 940 cm −1 are due to CH 2 scissoring and CH bending vibrations of pure PVAc, respectively.…”

Hybrid solid polymer electrolyte films comprising of poly(vinyl acetate) (PVAc), poly(methyl methacrylate) (PMMA), LiClO 4 , and propylene carbonate are prepared by solution casting technique by varying the salt concentration. In this study, PVAc/PMMA polymer blend ratio is fixed as 25:75 on the basis of conductivity and mechanical stability of the film. X-ray diffraction, Fourier transform infrared impedance, thermogravimetry/differential thermal analysis and scanning electron microscopy studies are carried out for the polymer electrolytes. The maximum ionic conductivity is found to be 4.511×10 −4 S cm −1 at 303 K for the plasticized polymer electrolyte with 8 wt.% of LiClO 4 . The ionic conductivity is found to decrease with an increase of LiClO 4 concentration.

“…However, the peaks exhibit changes in shift by further addition of BmImTFSI. It implies the weaker bonding within polymer matrix and thus accelerates the formation of complexation between polymer blends and BmImTFSI [24]. Change in intensity of the peaks is an indicative amorphous characteristic of polymer electrolytes.…”

“…The disappearance of the semi-circle in the high-frequency region leads to a conclusion that the current carriers are ions. This leads to a further conclusion that the total conductivity is mainly a result of ion conduction [9]. Besides that, this result also suggests that only the resistive component of the polymer electrolyte could be considered when the amount of salt solution is high.…”

Thin films of poly(methyl methacrylate) (PMMA) with lithium triflate (LiCF 3 SO 3 ) were prepared by using the solution-casting method with PMMA as the host polymer. Ionic conductivity and dielectric measurements were carried out on these films. The highest conductivity for polymer electrolyte with a ratio of 65:35 was found to be 9.88×10 −5 S cm −1 , which is suitable for the production of mobile phone battery. Thermal gravimetric analysis was carried out to evaluate the thermal stability of the polymer electrolyte. The addition of salts will increase thermal stability of the polymer electrolyte.
