Fig. 4. (a) Scheme illustrating the CNT fibre spinning from drawable CNT arrays by combining translation and rotation of the fibre, and (b) SEM image of vertically aligned CNT array
used for the CNT fibre spinning. (c) Optical image of the CNT fibre spinning from vertically aligned CNTs. (d) Scheme that illustrates a micro-slipknot. (e) SEM images of a typical
micro-knot of CNT thread. (A color version of this figure can be viewed online.)
