Effect of plasticizers on ionic conductivity and dielectric relaxation
The plasticizers having dielectric constants higher than PEO help to increase the ionic conductivity of PEO-LiClO 4 electrolyte. Addition of DMC in polymer matrix acts as an anti-plasticization effect due to low dielectric constant than that of the base polymer (PEO).
Effect of plasticizers on ionic conductivity and dielectric relaxation
In this paper, we report the effect of different plasticizers, such as poly ethylene glycol, propylene carbonate, ethylene carbonate and dimethyl carbonate on the ionic conductivity and dielectric relaxation of PEO-LiClO 4 solid polymer electrolytes. The highest ionic conductivity is obtained for polymer electrolyte plasticized with poly
Influence of succinonitrile plasticizer on ionic conductivity
As a plasticizer, succinonitrile (SN) has been utilized to improve the ion movement in the solid electrolytes. SN possesses a high dielectric constant (~54), low melting point (56 0 C) and plasticizing property at room temperature.
Influence of plasticizer on conductivity and dielectric properties
Variation of ionic conductivity with propylene carbonate. Initially, GG-SN complex was studied and a peak conductivity of 2.43 × 10-7 Scm 1 was achieved for 30 wt% of SN. Further incorporation of SN leads to the fall in conductivity caused by the formation of ion aggregate [7]. Then plasticizer effect is studied to improve the conductivity
- How does plasticizer affect ionic conductivity of polymer electrolytes?

- Does plasticizer increase ionic conductivity of PEC/Li?
- The DSC and BES studies revealed that the addition of plasticizer decreased Tg and increased the ionic conductivity of PEC/Li. The dc conductivity ( σdc) values of PEC/Li increased with the addition of plasticizers, and the plasti-cizing effect of IL was larger than that of Gly. From the results of the temperature dependencies of relaxation
