Multi-scale mechanical improvement produced in carbon nanotube fibers by irradiation cross-linking

摘要: Fibers and yarns based on carbon nanotubes (CNT) are emerging as a possible improvement over more traditional high strength fibers used reinforcement elements in composite materials. This is driven by desire to translate the exceptional mechanical properties of individual CNT shells achieve performance macroscopic yarns. One central limitations this approach weak shear interactions between adjacent tubes within Furthermore, multiple levels interaction, e.g., multi-walled or bundles fiber, compound problem. promising direction overcome limitation introduction strong stiff cross-linking bonds shells. A great deal research has been devoted studying such irradiation materials using either energy particles, electrons, directly covalently cross-link CNTs, electromagnetic irradiation, gamma rays strengthen polymer cross-links tubes. Here we review recent progress field irradiation-induced at with focus property improvements.
