Change of morphological properties in drawing water‐swollen cellulose films prepared from organic solutions. a view of molecular orientation in the drawing process

Cellulose in Never-Dried Gel Oriented by an AC Electric Field

“…It was shown that cellulose gel produced by slow coagulation over several hours is less than 20% crystalline. 17 The gel can be deformed easily up to a draw ratio of 2.0, and the obtained plastic deformation is highly persistent along with concurrent macromolecular orientation. 18 This agrees very well with the present observation of persisting orientation due to changes induced by an electric field.…”

“…It should be mentioned that the structure of the cellulose gel used for the present experiments is different from the structure of never-dried cellulose produced by rapid coagulation in the spinning bath. It was shown that cellulose gel produced by slow coagulation over several hours is less than 20% crystalline . The gel can be deformed easily up to a draw ratio of 2.0, and the obtained plastic deformation is highly persistent along with concurrent macromolecular orientation .…”

Erratum: Alemtuzumab by continuous intravenous infusion followed by subcutaneous injection plus rituximab in the treatment of patients with chronic lymphocytic leukemia recurrence

“…This observation agrees well with results obtained by drawing of highly amorphous never‐dried cellulose films,30 where no significant change in crystallinity was measured either. Togawa and Kondo30 propose that cellulose chains can not change their state from folded to fibrillar under strain due to the presence of intermolecular hydrogen bonding.…”

Miscibility studies of sodium carboxymethylcellulose/poly(vinyl alcohol) blend membranes for pervaporation dehydration of isopropyl alcohol

“…The first step was due to the loss of moisture. The second step was attributed to the disassociation of intermolecular side chains 36. The third weight loss was believed to be caused due to chemical reaction, such as main‐chain disassociation or rearrangement 36.…”
