Ultrahigh Strength and Stiffness in Cross-Linked Hierarchical Carbon Nanotube Bundles

Electron irradiation induced covalent cross‐linking at multiple length scales within double‐walled nanotube bundles is demonstrated to lead to ultrahigh effective strength and stiffness. In situ transmission electron microscopy tensile testing reveals both order of magnitude enhancements in the mech...

Description
Summary:	Electron irradiation induced covalent cross‐linking at multiple length scales within double‐walled nanotube bundles is demonstrated to lead to ultrahigh effective strength and stiffness. In situ transmission electron microscopy tensile testing reveals both order of magnitude enhancements in the mechanical properties as well as distinct failure mechanisms of cross‐linked versus un‐crosslinked bundles.
