Abstract
Disclosed is a fiber having a solid sheath and a liquid core. The liquid core has shear-thickening viscosity. Also disclosed is a method of electrospinning the fiber. The fiber may be useful for mechanical and sound damping.
Claims9
A fiber comprising:
- a solid sheath comprising poly (caprolactone);
- and
- a liquid core comprising a poly (ethylene glycol);
- wherein the diameter of the liquid core is non-uniform along the length of the fiber.
