Charge decay and relaxation times in electrets
53-54In the present communication, the decay
of surface charge density of bees wax and the role of a variety of relaxation
times in describing the nature of charge carriers have been studied in
detail. Thermo-electrets of bees wax were
prepared under different conditions of polarizing field, temperature and time.
The results of present investigations show that a single line does not fit the
complete exponential decay of the surface charge. The values of decay constants
range from 2.0×102 sec to 1.3×107 sec. Due to the
presence of a large number of dipoles and ions of different kinds in bees wax,
a number of dipole relaxation frequencies are expected
