length of the individual CNTs in the spinnable array is 450 mm, as
shown in Fig. 4b. Fig. 4c shows an image of the array and the fibre at
the twisting sites.
Fibre twist was applied to the drawn CNTs so as to form a uniform
cylindrical shaped thread. The fibres were prepared with
different twist angles, and with varying diameters for constant
twist angles. Different twist angles were obtained by varying the
draw and rotation speed while the array width was kept constant.
The uniform width of the synthezised CNT arrays was ensured by
the rectangular shape of the utilized Si wafer substrates. High twist
