Abstract :

Samples of poly vinyl acetate (PVA)–Polyol were blended by percentage of weight 3:1 and were mixed with different percentages by weight of prepared sulfonated–phenol formaldehyde resin (SPF) on clean glass substrate as a bulk films, with different thicknesses (0.1–0.18)x10–2 m. Diagnosis of SPF was determined by FTIR spectrophotometer. The current–voltage (I–V) characteristics and the potential across the bulk samples were measured at room temperature at applied electric field 13 volts dc. The electric field strength and, the current density were calculated and were investigated at time of measurements. The electrical conductivity was calculated, this was increased from (1.743x10–6, 6.756x10–3) S m–1 to (3.7, 185.8) S m–1. The minimum and maximum values are at (15, 40) wt% SPF and (15, 30) %wt SPF.
