Tuning hierarchically aligned structures for high-strength PMIA-MWCNT hybrid nanofibers

Nanoscale. 2013 Feb 7;5(3):886-9. doi: 10.1039/c2nr33696k. Epub 2012 Dec 17.

Abstract

Novel hierarchically aligned PMIA-MWCNT hybrid nanofibers with a robust tensile strength of 316.7 MPa were prepared by a facile electrospinning process. The critical roles of humidity and MWCNT contents in tuning hierarchically aligned structures were first proposed, and a two-step break mechanism upon external stress was confirmed.
