چکیده
The electrical resistance of cellulosic film is of particular importance in various application. In this study, the effect of nanosilica extracted from rice husk ash on the electrical conductivity of hydroxyethyl cellulose was investigated by using (Direct Current) DC electrical resistivity test. At first, the morphology of silica nanoparticles was analyzed using field emission scanning electron microscopy (FESEM), and also the morphology of nanocomposite films, dispersion and distribution of nanosilica in specimens were investigated using scanning electron microscopy (SEM). The result of this work, show that by increasing the amount of nanosilica from 0 to 18wt.% to the hydroxyethyl cellulose nanocomposite films, the DC electrical resistance reduces about 15%. This means that the addition of nanosilica particles to the cellulosic polymer improves the DC electrical conductivity of the polymer.
