Abstract
Amethod of fabricating a continuous nanofiber is described . The method includes preparing a solution of one or more polymers and one or more solvents and electrospinning the solution by discharging the solution through one or more liquid jets into an electric field to yield one or more continuous nanofibers . The electrospinning process ( i ) highly orients one or more polymer chains in the one or more continuous nanofibers along a fiber axis of the one or more continuous nanofibers , and ( ii ) suppresses polymer crystallization in the one or more continuous nanofibers . The one or more continuous nanofibers can have diameters below about 250 nanometers and exhibit an increase in fiber strength and modulus while maintaining strain at failure , resulting in an increase in fiber toughness.
