  Volume Fraction of Ether Is a Significant Factor in Controlling Conductivity in Proton Conducting Polyether Based Polymer Sol–Gel Electrolytes

  摘要：

  We have synthesized several copolymers of methyl polyethylene glycol siloxane (MePEG(7)SiO(3))(m) and methyl polypropylene glycol siloxane (MePPG(n)SiO(3))(m) as hydrogen ion (H+) conducting polymer electrolytes. These copolymers were prepared by a solgel polymerization of mixtures of the MePEG and MePPG monomers. We synthesized these H+ conducting polymer electrolytes in order to study the relationship between observed ionic conductivity and structural properties such as viscosity, fractional free volume, and volume fraction of ether. We found that viscosity increased as the fraction of the smaller comonomer increased. For the MePPG(2)/MePPG(3) copolymer, an increase in fractional free volume increased the fluidity. The heterogeneous copolymers (PEG/PPG copolymers) obeyed the Doolittle equation, while the homogeneous (PEG/PEG and PPG/PPG) copolymers did not. The increase of FFV did not, however, correspond to an increase in conductivity, as would have been predicted by the Forsythe equation. The conductivity data did correspond to a modified Forsythe equation substituting Volume Fraction of Ether (V-f,V-ether) for FFV. We conclude that the proton conductivity of MePEG copolymers is more dependent on the volume fraction of ether than on the fractional free volume.
