N. Sen Sarma et Nn. Dass, Measurement of ionic conductivity of some electrolytes polyelectrolytes and complexes in solid state, I J PA PHYS, 37(4), 1999, pp. 321-324
The paper reports the ac conductivity of some new compounds like poly (viny
l borate), P-1 and its metal derivatives, hexakis DMSO Fe (III) fluoroborat
e, F-1 and its bromide derivative, F-2, cast in the solid state. The format
ion of the compounds was confirmed by IR and H-1 NMR spectra. The conductiv
ity study indicated that the mechanism for conduction in all the above mate
rial was mainly ionic. It was observed that the ac conductivity of P-1 and
its metal derivatives, increased with the rise of frequency in contradictio
n with the F-1 and F-2 which showed reverse trend. Conductivities were dete
rmined varying temperature too, in the range of 24 degrees C to 40 degrees
C. Conductivities of P-1, P-1-Na, P-1-K and P-1-Al at 25 degrees C were fou
nd to be 2.191 x 10(-6), 4.823 x 10(-9), 7.321 x 10(-9) and 11.714 x 10(-11
) Omega(-1) mm(-1), respectively. The corresponding conductivities at 40 de
grees C were 5.634 x 10(-6) 19.894 x 10(-9), 30.770 x 10(-9) and 21.008 x 1
0(-11) Omega(-1) mm(-1), respectively. For samples F-1 and F-2 the results
were in the range of 10(-9) and 10(-7) Omega(-1) mm(-1), respectively. Cond
uctivities were found to be increased with the rise of frequency. But a rev
erse trend was observed for bromide derivative of F-1.
