Abstract

Disclosed are methods of forming a plurality of fibers, and nanofibers produced from such a method.

Claims

exact text as granted — not AI-modified
1 - 38 . (canceled) 
     
     
         39 . A nanofiber, wherein the diameter of the nanofiber is about 1 nm to about 1 μm. 
     
     
         40 . The nanofiber of  claim 39 , wherein the yield stress of the nanofiber is in the range from about 2 GPa to about 100 GPa. 
     
     
         41 . The nanofiber of  claim 39 , wherein the diameter of the nanofiber is about 10 nm to about 1 μm. 
     
     
         42 . The nanofiber of  claim 39 , wherein the diameter of the nanofiber is about 100 nm to about 1 μm. 
     
     
         43 . The nanofiber of  claim 39 , wherein the diameter of the nanofiber is about 10 nm to about 500 nm. 
     
     
         44 . The nanofiber of  claim 39 , wherein the diameter of the nanofiber is about 100 nm to about 500 nm. 
     
     
         45 . The nanofiber of  claim 39 , wherein the Young's modulus of the nanofiber is in the range from about 85 GPa to about 1000 GPa. 
     
     
         46 . The nanofiber of  claim 45 , wherein the Young's modulus of the nanofiber is in the range from about 90 GPa to about 1000 GPa. 
     
     
         47 . The nanofiber of  claim 45 , wherein the Young's modulus of the nanofiber is in the range from about 95 GPa to about 1000 GPa. 
     
     
         48 . The nanofiber of  claim 45 , wherein the Young's modulus of the nanofiber is in the range from about to 100 GPa to about 1000 GPa. 
     
     
         49 . (canceled) 
     
     
         50 . The nanofiber of  claim 40 , wherein the yield stress of the nanofiber is in the range from about 3 GPa to about 100 GPa. 
     
     
         51 . The nanofiber of  claim 40 , wherein the yield stress of the nanofiber is in the range from about 4 GPa to about 100 GPa. 
     
     
         52 . The nanofiber of  claim 40 , wherein the yield stress of the nanofiber is in the range from about 5 GPa to about 100 GPa. 
     
     
         53 . The nanofiber of  claim 40 , wherein the yield stress of the nanofiber is in the range from about 6 GPa to about 100 GPa. 
     
     
         54 . The nanofiber of  claim 40 , wherein the yield stress of the nanofiber is in the range from about 7 GPa to about 100 GPa.
