The crystal structure of Erythrosine B /PVA films was identified by X-ray diffraction patterns (XRD). The frequency (100 Hz - 1 MHz) reliance on both dielectric constant (ε1) and dielectric loss (ε2) was investigated. Both ε1 and ε2 of Erythrosine B/PVA polymeric composite films decreased with increasing frequency and increased by rising percent EB wt%. The ac conductivity of erythrosine B/PVA films showed increased behavior by raising both frequency and temperature. Moreover, frequency exponent (s) values were calculated and then discussed according to the CBH system, which is the fundamental model. Values of the maximum barrier height (W M ) and ac Activation energy (∆E ac ) were calculated for the different concentrations of wt% EB in investigated films. ∆E ac decreased from 95 to 17 meV for 1wt% EB and 4 wt% EB, respectively.
