preparation example Construction

[0151] The invention also provides a preparation method of the composite ink. Wherein, the composite ink can adopt the following two preparation methods.

[0152] For example, the three-dimensional dendrimer conjugated compound is first dissolved in at least one solvent, and then the commercial large-diameter P2 single-walled carbon nanotubes are uniformly dispersed in the second The three-dimensional tree-shaped conjugated compound solution prepared in one step is finally subjected to short-term high-speed centrifugation, and the supernatant is separated to obtain an ink solution enriched in semiconductor-type large-diameter commercial carbon nanotubes.

[0153] For example, first mix the three-dimensional dendrimer conjugated compound with other organic semiconductor materials, and then dissolve them together in an organic solvent, and then disperse them evenly under the condition of temperature ≤ 0°C, and finally perform short-term high-speed centrifugation , separate the ...
