  • Publication number: 20200102670
    Abstract: The invention provides networked polymeric nanofibers having a structure in which amorphous polymeric fibers are branched at multiple sites and having a diameter of from 1 nanometer to 100 nanometers. A solution of a polymer such as polystyrene in a good solvent thereof is rapidly frozen to form a nanoscale phase-separation structure of the polymer and the frozen solvent. The networked polymeric nanofibers can then be obtained upon removing the frozen solvent.

  • Patent number: 8945391
    Abstract: The object of the invention is to provide an organic polymers-separation membrane filter capable of physically separating organic polymers based on their molecular stereostructure difference without giving rise to chemical changes in them and without selecting their chemical compositions. The organic polymers-separation membrane filter comprising an ultrafilter membrane is characterized in that a path taken by a nano permeation pore has a narrower path portion having a width narrower than that of the rest, wherein organic polymers capable of changing in their stereostructure are passed through the path while their width is transformed into a configuration along the narrower path portion, thereby separating the organic polymers. In the ultrafilter membrane, particulate materials are mutually coupled together in its thickness and planar directions. The particulate materials comprise a protein.
