1. Introduction
Structures common in nature are often multilevel and hierarchical, tuned to the desired functionality at a minimal cost in resources. For example, bone structure is a self-assembled, seven levels composite, which evolved to achieve a balance between toughness and stiffness at a low weight [1]. A natural surface can be adhesive as in the attachment pads on a gecko's foot [2], or repellent as in a lotus leave [3], as a result of different structural hierarchies. Attempts at bio-inspired synthetic composites have not been successful so far, and the performance and efficiency of such composites are far behind their natural counterparts or theoretical prediction. The application of nanocomponents such as carbon nanotubes (CNTs) [4] as reinforcing materials is still limited to lab scale, mainly due to technical obstacles related to their dispersion and alignment in matrices and to their matrix interface [5]. Recently, a new reinforcing component has been proposed in parallel by several groups, exploiting fibers that consist of millions of bundled CNTs (Fig. 1) [6]. These CNT fibers, or CNTFs, are produced by spinning CNTs either from a CNT aerogel [7], or from a CVD-grown CNT array [8], or by coagulation of a CNT-containing polymer solution [9]. Because of the tension and shear forces induced by pulling, twisting and extrusion, the CNTs are well aligned and tightly packed within the CNTF. In addition to high loading (100% CNTs), better alignment, infinite length, and easy handling, CNTFs are flexible, reliable fibers with mechanical and electrical properties that can be tuned by production conditions [10,11]. CNTFs have a compact twisted yarn-like hierarchical structure, spanning across multiple length scales from nanoscale to micro- and macroscale [6,12,13]. The mechanical, electrical and thermal properties of CNTF based composites are affected by the CNTF densification and polymer impregnation [13e15]. These unique structural features allow CNTFs to be a potentially
