Preparation and characterization of plasticized high molecular weight PVC-based polymer electrolytes

Abstract

Poly(vinyl chloride) (PVC)-based polymer electrolytes films consisting of lithium trifluromethanesulfonate (LiCF 3 SO 3 )-ethylene carbonate (EC) were prepared by the solution-casting method. Ionic conductivities of the electrolytes have been determined by an impedance studies in the temperature range of 298-373 K. Complexation of the prepared electrolytes is studied by X-ray diffraction (XRD) analysis. Thermogravimetric analysis (TGA) was used to confirm the thermal stability of the polymer electrolytes. The conductivity-temperature plots were found to follow an Arrhenius nature. All these films are found to be thermally stable until 132-167 • C.

Preparation and characterization of plasticized palm-based polyurethane solid polymer electrolyte

“…The soft segment of the polymer chains facilitated the ion mobility in a polymer electrolyte formed by the dissolution of ions in the polymer. The effective number of carrier ions is related to the concentration of the dissolved ions [1]. …”

“…The amorphous region or the reduction of the crystalline region would result in high ionic conductivity compared to the crystalline and semi-crystalline region [1,11]. The effect of salt complexation of PULiCF 3 SO 3 system was studied by performing XRD analysis of the system which was added with 5 wt.…”

“…The advantages of polymer electrolyte are their elasticity, ease of processing into thin films of large surface area, electrochemical stability and leak-proof nature which make it applicable for batteries, fuel cells, supercapacitors, electrocromic devices and chemical sensors [1]. An excellent polymer electrolyte should have a low degree of crystallinity, while a good mechanical property should be maintained for practical applications and ease of film fabrication [2] During the formation of polyurethane, diisocyanate crosslinks with polyether monomer to form a segmented polymer having a general structure (A-B) n , where B is the soft segment that formed from one or more of polyether or polyester polyol and A is the hard segment formed by extending a diisocyanate with low molecular weight diol or diamine [3].…”

“…In polymer complexes, these peaks of PVC appeared as a single broad peak with less intensity indicates that the synthesized microporous PVC membrane is highly amorphous in nature 13 .…”

Effect of plasticizer on conductivity and cell parameters of (PMMA+NaClO4) polymer electrolyte system

“…In recent years, polymer electrolytes have been widely studied due to their applicability for a variety of solid state and electrochemical device applications including batteries, fuel cells, supercapacitors, electrochromic devices and chemical sensors [1][2]. Solid polymer electrolytes have many advantages, such as no leakage, volumetric stability, ease of fabrication of thin films of desired size, and wide electrochemical stability windows [3].…”
