K. Nitsch et al., IMPEDANCE SPECTROSCOPY OF CARBON BLACK-FILLED POLYESTERIMIDE THICK-FILMS, International journal of electronics, 76(5), 1994, pp. 981-986
Impedance spectroscopy in the frequency range from 10 mHz to 10 MHz ha
s been used to analyse carbon black-filled polyestrimide thick films.
The influence of carbon content (below, near and over percolation thre
shold) and curing temperature are discussed. Electrical equivalent cir
cuits representing physically acceptable models are presented for part
icular films, and values of circuit elements are estimated and compare
