Abstract: A fiber that has a unique surface topography in that it contains a plurality of nanohairs extending outwardly from an external surface of an elongate structure of the fiber is provided. To form the nanohairs, a polymer composition is spun that includes organofunctional nanoparticles (e.g., polyhedral organofunctional silsesquioxanes) embedded within a matrix of a base polymer. Despite being initially embedded within the polymer, the present inventors have discovered that, through selective control over the nature and relative concentration of the components of the composition, as well as the method in which the fiber is formed, a substantial portion of the nanoparticles can migrate to the surface of the fiber as it is formed and thus become arranged in the form of nanohairs.
