Polymer-Carbon Nanotube Composite Fibers with Ultrahigh Dynamic Strength

Abstract

Ultrahigh dynamic strength fibrous materials are very vital for applications in high-strain rate environments. A recent research article on Science highlights a significant advancement in polymer-carbon nanotube composite fibers, which developed a new strategy to fabricate fibrous materials with an unprecedented dynamic strength of 14 GPa by optimizing hierarchical structures. This work provides fresh mechanism insights and an effective strategy to harness the intrinsic strength of individual carbon nanotubes at the macroscale, and marks a dramatic breakthrough in the realm of ultrahigh-strength fibers.
