| Summary: | The potential of electrolytes’ performance in electrochemical devices is among the leading research. There are
several ways to improve the conductivity of electrolytes, including the employment of additive materials and
polymer blends. This research aims to improve the conductivity of a polymer blend with quasi solid state
electrolyte. Poly-methyl methacrylate (PMMA) and poly-vinylidene fluoride (PVdF) possed great electrochemical
stability and thermal stability. Hence, these materials were chosen as the target polymer for the synthesis of the
polymer blend. The electrical impedance spectroscopy (EIS) analysis showed an optimum conductivity value of
3.44 × 10− 6 Scm− 1 with the ratio of PMMA: PVdF (70:30) at ambient temperature. The dependent temperature
of PBE was also analyzed to prove that the conductivity increases with the increment of temperature and low
activation energy (Ea). The thermogravimetric analysis (TGA) shows the stability of PBE up to 651 ◦C. Through
this research, there are several different concentrations of PBE to investigate the stability of PBE with great value
in the conductivity performance. |
