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.
