Poly(vinyl) chloride (PVC)-NH4I-EC films have been prepared by solution cast technique. The sample containing 30 wt. % NH4I exhibited highest room temperature conductivity of 4.60 × 10-7S cm-1. The conductivity increased to 1.08 × 10-6Scm-1when 15 wt. % of ethylene carbonate (EC) was added to 70 wt. % PVC - 30 wt. % NH4I. Fourier Transform Infrared (FTIR) showed evidence of polymer–salt complexation while DSC showed increase in glass transition temperature (Tg) of PVC -NH4I - EC polymer electrolytes. The conductivity behavior of the studied system could be accounted by the changes in Tgvalues.

Films of chitosan polymer doped with lithium acetate dihydrate (LiOAc.2H2O) and placticized with oleic acid (OA) and palmitic acid (PA) were prepared by the solution cast technique. The film containing 40.0 wt. % LiOAc and 10.0 wt. % of OA exhibit a room temperature conductivity of ~ 10-5 S cm-1 and the film containing 41.0 wt. % LiOAc and 7.7 wt. % of PA has conductivity ~ 10-6 S cm-1. The plot of ln(sT) versus 103/T for the highest conducting samples obey an Arrhenian relationship in the temperature range between 300 and 363 K implying that the conductivity is thermally assisted. FTIR spectroscopy and XRD techniques have been used for the complexation studies. The LiNiCoO2/chitosan-LiOAc-OA/MCMB electrochemical cell could be charged to a voltage of 4.2 V.

Solution Casting Method

Solid biopolymer electrolytes (SBE) comprising carboxymethyl cellulose (CMC) with NH4Br-EC were prepared by solution casting method. The samples were characterized by impedance spectroscopy (EIS) and sample containing 25wt. % of NH4Br exhibited the highest room temperature conductivity of 1.12 x 10-4S/cm for salted CMC based SBE system. The ionic conductivity increased to 3.31 x 10-3S/cm when 8 wt. % of ethylene carbonate (EC) was added to the highest conductivity. The conductivity-temperature of plasticized SBE system obeys the Arrhenius relation where the ionic conductivity increases with temperature. The influence of EC addition on unplasticized CMC based SBE was found to be dependent on the number and the mobility of the ions. This results revealed that the influence of plasticizer (EC) which was confirmed play the significant role in enhancement of ionic conductivity for SBE system.

Cast Technique

In this work, the film contained a mixture of PMMA, salt, and plasticizers are studied. PMMA as a host polymer, ammonium trifluoromethane sulphonate or ammonium triflate (NH4CF3SO3) as a doping salt and ethylene carbonate (EC) as a plasticizer is used in this present study. PMMA salt complexes system and plasticized PMMA salt complexes system are prepared by solution cast technique at room temperature. FTIR is used to study the interaction between polymer and salt, and between polymer–salt and plasticizer. The carbonyl group C=O asymmetric stretching mode observed at 1721 cm-1 is broadened and shifted to lower wavenumber when ammonium triflate was added into PMMA. The broadening, shifting and reduction in wavenumbers of FTIR spectra show that the complexation has occurred between the polymer and salt. EIS is performed to measure the electrical conductivity of the polymer–salt system prepared at ambient temperature. The electrical conductivity of film containing 1.0 g of PMMA–35 wt% NH4CF3SO3–16 wt% EC exhibit the highest electrical conductivity with the value of 2.461 x 10-4 S/cm2. XRD is carried out to study the pattern of pure PMMA, PMMA–NH4CF3SO3 and PMMA–NH4CF3SO3–EC. The XRD analysis shows the addition of plasticizer to the polymer–salt system increase the amorphousness of the polymer electrolytes hence increases in conductivity.

Cast Technique

The conducting polymer electrolyte films composed of polyacrylonitrile (PAN) as the host polymer, LiCF3SO3 and NaCF3SO3 as inorganic salts and ethylene carbonate (EC) as plasticizer were prepared by the solution cast technique. The conductivities of the films were characterized by impedance spectroscopy. On addition of more than 14 wt% of salt, the NaCF3SO3-containing PAN films exhibited higher ionic conductivity than the LiCF3SO3-containing PAN films. The values of the dielectric constant, εr and dielectric loss, εi increase as frequency decreases at room temperature. The temperature dependence of the conductivity obeys Arrhenius relation in the temperature range of 303 K to 353 K.

Abstract Three novel soluble copolymers of poly(3-penthylthiophene) [P(3PT)] and poly(3-phosphate diethyl 3-thienylmethyl) [P(3FT)] of different molar ratios of co-mers (3:1, 1:1 and 1:3) have been chemically synthesised. The final copolymers were obtained by functionalisation of poly(3-penthylthiophene-co-3-bromomethylthiophene) [P(3PT-co-3BT)] copolymers, because P(3FT) monomer does not couple in position 2-5′ of the copolymers. The structure and physical-chemical properties of resulting polymer was investigated by nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR), visible and ultraviolet spectroscopy (UV-Vis), photoluminescence and direct current (DC) measurements. By changing the molar ratios of monomers during synthesis we can “tailor” the photoemission of resulting copolymers. The room temperature conductivity distinctly increases after doping by electrons’ acceptor. The polymers studied are good candidates for potential commercial applications.

The present work investigated the effect of carboxy methylcellulose (CMC) solid polymer electrolytes doped with ammonium carbonate (AC) prepared from solution cast technique. The CMC-AC solid polymer electrolytes system has been analyzed using EIS to understand its conductivity and dielectric behavior at temperature range of 303 K to 363 K. The highest conductivity achieved at room temperature (303K) is 7.71 x 10-6S cm-1doped with 7wt.% of AC and all samples follows Arrhenius behaviour. The dielectric constant (εr) value was found to be dependent of ionic dopant.
