## Abstract Cellulose fibers with modified properties have been prepared from cellulose solutions in __N__βmethylmorpholineβ__N__βoxide (NMMO). Poly(ethylene oxide) as a hydrophilic modifier and polyethylene as a hydrophobic modifier were added to the spinning solution. Based on microscope examinat
The N-oxide group of the cellulose solvent N-methylmorpholine-N-oxide showed a strong preference for the axial position compared with N-methyl as determined by NMR experiments and computational studies. In solvents with negligible solvent -solute interaction, about 95% of the NMMO molecules obtained
## Abstract Cellulose membranes were obtained by solutions of cellulose being cast into a mixture of __N__βmethylmorpholineβ__N__βoxide (NMMO) and water under different processing conditions. Atomic force microscopy (AFM) was used to investigate the surface structures of the membranes. The AFM meth
