Abstract
DC electrical conductivity was measured from room temperature to about 230°C for Cellulose I and Cellulose II. The conductivity vs. temperature curve showed a break at about 150°C for Cell I and at about 80°C for Cell II. The break points corresponded to those observed previously in the spacing vs. temperature curves. These phenomena may possibly be associated with the second order transition at which the restricted motion of chain segments in the crystals begins to acquire high mobility. The conductivity in the fiber axis direction was approximately ten times as large as that in the perpendicular direction.
