Embodiment Construction
[0022] Various embodiments of the nanoscale microstructure and its preparation method will be further described in detail below in conjunction with the accompanying drawings.
[0023] see figure 1 , the first embodiment of the present invention provides a method for preparing a nanoscale microstructure, which includes the following steps:
[0024] Step S10, providing a carbon nanotube structure 110, the carbon nanotube structure 110 comprising a plurality of carbon nanotubes arranged in an orderly manner;
[0025] Step S20, setting the carbon nanotube structure 110 in the air;
[0026] Step S30, setting a prefabricated layer 120 on the surface of the carbon nanotube structure 110, so that the thickness of the prefabricated layer 120 on the surface of each carbon nanotube is 2 nanometers to 10 nanometers, so as to obtain a carbon nanotube composite structure 130;
[0027] Step S40, transferring the carbon nanotube composite structure 130 to the surface of a substrate 140, and...
