“…10(a) and 1 l(a), respectively. Inter-CNT sliding can be clearly observed in the fracture area, and the fracture morphologies are very much similar to the those observed in experiments [33,34]. Some snapshots representing the key structural evolutions during the fiber stretching are shown in Eigs.…”

Coarse-grained molecular dynamics simulations have been peiformed to investigate the tensile behavior of CNT films. It is found that CNT entanglements greatly degrade the tensile load-bearing capability of CNT films. The effect of twisting on the tensile behavior of CNT fibers spun from CNT films has also been investigated. Results indicate that twisting can make either positive or negative contributions to the mechanical properties of the film, depending on the microstructure. The structural and energy evolution of CNT films and fibers, as well as the stress distributions ofCNTs which cannot be easily determined experimentally, have been illustrated. This study provides an effective means of revealing the structure/property relationships of CNT films/fibers, which are essential in designing high performance CNT fibers.

“…Despite the variety of structural approaches tested thus far, raw CNTYs still show poor properties due to the interfacial slippage among bundles or CNTs [7,8]. Recent studies have modified the CNT surfaces using chemical reactions to introduce covalent or hydrogen bonds, which are stronger than the van der Waals interactions, in an effort to enhance the interfacial strength [18][19][20]. The functional groups introduced onto the CNT surfaces are essential for inducing bonding sites [21], and they provide a powerful http://dx.doi.org/10.1016/j.carbon.2015.02.065 0008-6223/Ó 2015 Elsevier Ltd.

Focused ion beam (FIB) milling through carbon nanotube (CNT) yarns and bucky-papers followed by scanning electron microscopy has recently emerged as a powerful tool for eliciting details of their internal structure. The internal arrangement of CNTs in bucky-papers and yarns directly affects their performance and characteristics. Consequently this information is critical for further optimisation of these structures and to tailor their properties for specifi c applications. This chapter describes in detail FIB milling of CNT yarns and bucky-papers and gives a range of examples where FIB milling has enabled a better understanding of how processing conditions and treatments affect the internal structure. Emphasis is placed on how FIB milling elucidates the infl uence of fabrication conditions on the internal arrangement of CNTs and how this infl uences the material's macroscopic properties.
