Abstract:
      Cellulose is the most abundant natural polymer in nature， with many advantages such as structural stability， recyclability and biodegradability. Natural cellulose polymers have high crystallinity and single function， which is difficult to be applied in a wide range and many fields. Dissolved cellulose macromolecules can be rearranged into cellulose materials with special structures and properties under specific regeneration conditions. The solvent selection and regeneration process of cellulose have a certain degree of influence on the morphology， crystal structure， crystallinity and thermal stability of regenerated cellulose. Regenerated cellulose is easy to carry out various chemical reactions， which is of great significance for expanding the application ranges of cellulose. Therefore， the effects of different non-derivative solvents and regeneration processes （regenerative solvents， regeneration temperature， regenerative humidity） on the structures and properties of regenerated cellulose was reviewed in this paper.
