| 抄録: | New proton-conductive polyamide oligomers, oligomeric poly[(1,2-propanediamine)-alt-(oxalic acid)], were synthesized to investigate the proton transport properties of bulk and thin films. The obtained oligomers were characterized by the X-ray diffraction, FT-IR spectra, ^<1>H NMR, Matrix Assisted Laser Desorption / Ionization Time of Flight (MALDI-TOF) mass spectrum, and electrical conductivity measurements. The bulk proton conductivity is 3.0 × 10^<-4> S cm^<-1> at the relative humidity (RH) of 80 %. The proton conductivity of thin film is relatively higher than that of bulk sample. Thickness dependence of the proton conductivity was observed in these thin films. The maximum proton conductivity of the thin film is 4.0 × 10^<-3> S cm^<-1> at the relative humidity (RH) of 80 %, which is higher one order magnitude than that of the bulk sample. The activation energies of bulk and 200 nm thick film are 1.0 and 0.69 eV at the RH of 60 %, respectively. |
