Article Synopsis
- The cold alkaline treatment (mercerization) of cellulose is used in industry to enhance the material by removing hemicelluloses, leading to a structural transition from cellulose I to cellulose II.
- Cellulose II is characterized by an antiparallel arrangement of macromolecules, which is seen in both mercerized and regenerated cellulose, but the formation of this structure during mercerization is significantly complex.
- This paper examines theoretical challenges concerning the antiparallel structure of mercerized cellulose, compiling existing experimental findings to support the discussion.
Man-made fibers were spun from solutions of cotton and wood cellulose in ionic liquid (1-butyl-3-methyl-imidazolium chloride, [B]Cl). Depending on the concentration, cellulose dissolved in [B]Cl down to macromolecules or nanofibrils. The artificial fibers had a diameter of about 100 nm, were uniform, transparent, helical, and optically active.
