| Outline of Final Research Achievements |
Cellulose acetate (CA) membranes with surface-modified cellulose nanofibrils (CNFs) were designed for water purification systems. Surface-modified TEMPO-oxidized CNFs dispersed in organic solvents were added to cellulose acetate solutions. CA membranes with CNFs were prepared by phase inversion process. Pure water flux and solute permeability of the membranes were measured using a cross-flow filtration system. The water permeability, porestructures and mechanical properties of the membranes were changed by adding CNFs. These results indicate that the surface modification of CNFs have an important role for increasing the affinity between CA and CNFs.
