| Outline of Final Research Achievements |
Nanofiber/polymer composite membranes were prepared, and the additive effect of nanofibers on the membrane morphology and transport property was investigated. When hydrophilic nanofibers were homogeneously dispersed in the polymer matrix, the water flux increased without reducing salt rejection. On the other hand, it was found that hydrophobic nanofiber surfaces induce water motion suppression. These results indicate that the incorporation of well-dispersed hydrophilic nanofibers in polymer matrix provides a promising and facile option for improvement in the water transport properties through the membranes.
