摘要：

Films of polyethyleneoxide (PEO) complexed with ammonium perchlorate (a proton conductor) were prepared from methanol solutions. The IR spectral studies confirmed the complexation in the PEO-NH4ClO4 system. The solution casted polymer films were partially crystallized at room temperature. Further, PEO shows limited solubility of NH4ClO4 as it was found to crystallize out at higher concentrations. The highest room temperature conductivity (≈10-5 S cm-1) has been observed in the composition range of NH+4 EO ratio (0.02-0.1). The conductivity is strongly humidity dependent. The σ versus 1/T plots show a sudden increase in conductivity at Tm≈60°C. © 1990.
