Abstract:
1. A carbon nanotube precursor comprising: a substrate; a carbon nanotube array comprising a plurality of carbon nanotubes on the substrate; and at least one separating line; wherein at least one strip-shaped carbon nanotube array is defined in the carbon nanotube array by the at least one separating line, a length of the at least one strip-shaped carbon nanotube array is greater than a largest width of the carbon nanotube array, the at least one separating line comprises a plurality of semicircular lines joined end-to-end, circular centers of the plurality of semicircular lines lay on a datum line, the plurality of semicircular lines have a diameter increasing along a direction from a geometric centre of the carbon nanotube array to an edge of the carbon nanotube array, a largest diameter of the plurality of semicircular lines is equal to the largest width of the carbon nanotube array.
