The effect of silylation of cellulose on electrical properties is investigated by tracing the changes occurred in the dielectric constant, dielectric loss and the activation energy of dielectric relaxation. The test samples are activated cellulose with ethylene diamine, with sodium hydroxide and unactivated cellulose before and after silylation. The measurements are carried out within the frequency band 10 5 to 10 7 Hz and the temperature range from 10 to 50 0C using multi-deka-meter. Cellulose molecules are more activated by treatment with ethylene diamine than with sodium hydroxide. Generally, silylation causes a marked decrease of the dielectric constant and dielectric loss, meanwhile the silylation samples are affected with the pretreatment of linters with sodium hydroxide and ethylene diamine.

Abstract
The effect of silylation of cellulose on electrical properties is investigated by tracing the changes occurred in the dielectric constant, dielectric loss and the activation energy of dielectric relaxation. The test samples are activated cellulose with ethylene diamine, with sodium hydroxide and unactivated cellulose before and after silylation. The measurements are carried out within the frequency band 10 5 to 10 7 Hz and the temperature range from 10 to 50 0C using multi-deka-meter. Cellulose molecules are more activated by treatment with ethylene diamine than with sodium hydroxide. Generally, silylation causes a marked decrease of the dielectric constant and dielectric loss, meanwhile the silylation samples are affected with the pretreatment of linters with sodium hydroxide and ethylene diamine.
