Embodiment 1
[0043]The preparation and characterization of polymer nanowires with controllable molecular orientation mainly include the following five steps, such as figure 2 shown.
[0044] Step S1, preparing a nanoporous alumina template, wherein the template has nanocylindrical holes in a hexagonal arrangement, and the diameter of the nanoholes is 10-1000 nanometers;
[0045] The anodized aluminum template is an inorganic metal oxide template with nano-cylindrical holes. The nano-cylindrical holes in the template are arranged in a hexagonal manner, and its scanning electron microscope image is shown in figure 1 shown.
[0046] Anodized aluminum templates are prepared by a two-step anodization method. The diameter of the nanopores in the inorganic alumina template can be adjusted by selecting different electrolytes and voltages. The inorganic alumina template component is alumina, and its surface tension is much greater than that of the polymer. Therefore, the semiconducting polyme...
