Electrical conduction in nylon fibre and cellulosic capacitor tissue
The experiments described in this work are divided into two main
parts. The first is concerned with electrical properties of a
single filament of nylon held between two tungsten hook-electrodes.
Currents were observed in atmospheres of different relative humidities and attempts were made to determine the voltage distribution
along the filament. The voltage measurements were made using
a high-impedence electrostatic null detector with a potentiometer
system for balancing. The results were not highly reproducible
and no definite conclusions could be made.
The second part deals with currents through capacitor tissue in a
metal- insulation- metal sandwich arrangement. A time-dependent
polarization was observed and is discussed along with methods for
determining an acceptable value for the steady-state current. Some
attempts are made to apply Poole-Frenkel theory since there is a
certain quantitative agreement with experiment. Current-temperature
observations indicated that the activation energy is about 1 ev.
Conclusions concerning the mechanism of conduction are suggested on
the basis of available theory
