Dielectric behavior of paper sheets prepared from rice straw pulp bleachedby nonconventional H2O2 method

The dielectric behavior of paper sheets prepared from rice straw pulp bleac hed by a nonconventional hydrogen peroxide method has been studied. The die lectric behavior is discussed. On the other hand, the dielectric relaxation time tau, activation energy Delta H epsilon,, and entropy change as, for t he dielectric relaxation are calculated. It was found that the mechanical p roperties of the paper calculated as the quality number are related to the dielectric properties as well as to the thermodynamic parameters which depe nd on the bleaching media of the pulp.
