| Research Abstract |
Free-standing thin films with a thickness of a few tens to hundreds nanometers were prepared by filtering dilute solutions of nanocomposite fibers that were made of metal hydroxide nanostrands and proteins. The mechanical strength of the films was largely improved by cross-linking the proteins. The films showed filtration performance three orders of magnitude improved from the previous size-selective ultrafiltration membranes for organic molecules. We also prepared free-standing films of latex particles and network polymers by using the similar method and developed ultrafiltration membranes with superior separation properties for proteins.
