AbstractAn accelerating potential of 75 kV combined with very low beam current and exposure time of 5 sec seem ideal for recording electron diffraction pattern of cooled specimens of cellulose microfibrils. Over 16 reflections could be seen distinctly. The structural parameters of ordered regions were: 89 crystallinity index, 72 Å crystallite width, and 209–230 Å crystallite length. Even the diffraction pattern of the uncooled specimen at 75 kV had a large number of reflections and was superior to those recorded on the cooled specimen at 50 or 100
