The aim of present investigation is to study the behavior of electrical properties and ac conductivity of Shorea robusta wood species as a function of chemical treatment (NaOH) at different concentrations 3%, 6%, 9%, 12% and 15%.Frequency dependence of dielectric parameters like dielectric constant, dielectric loss and ac conductivity of the composites were investigated in the frequency range from 100Hz to 1MHz at different concentrations. The results showed that the chemical treatment effect on Shorea robusta wood species lowers its dielectric constant and dielectric loss with concentration compared to untreated wood. It was also found that dielectric constant and dielectric loss factor values decreased with increase in frequency of the applied field. However, the ac conductivity of all wood samples is found to increase with increase in frequency.
