    摘要: According to one aspect of the invention, multicomponent fiber are provided, which comprise (a) a polymeric core that comprises a core-forming polymer and (b) a polymeric sheath that comprises a sheath-forming polymer that is different than the core-forming polymer. Examples of core-forming polymers include, for instance, crosslinked polysiloxanes and thermoplastic polymers, among others. Examples of sheath-forming polymers include, for instance, solvent-soluble polymers, degradable polymers and hydrogel-forming polymers, among others. Other aspects of the present invention pertain to methods of forming such multicomponent fibers. For example, in certain preferred embodiments, the multicomponent fibers are formed using coaxial electrospinning techniques. Still other aspects of the present invention pertain to meshes and other articles that are formed using the multicomponent fibers.

    摘要: Devices and methods for high-throughput manufacture of concentrically layered nanoscale and microscale fibers by electrospinning are disclosed. The devices include a hollow tube having a lengthwise slit through which a core material can flow, and can be configured to permit introduction of sheath material at multiple sites of Taylor cone formation formation.
