Problems solved by technology

However, these methods are usually accompanied by the transfer of substances, which will lead to changes in the surface morphology of the material, and further cause the residue generated by the probe scribing to accumulate on both sides of the scratch, increasing the line width of the scratch and thus Affect machining accuracy, etc.
At present, there is still no suitable method to construct nano-conductive patterns without changing the surface morphology of conjugated polymers.

Abstract

The invention discloses a method for constructing a conjugated polymer nano-conductive pattern by a scanning probe. The method comprises the following steps that: preparing, heating and fully dissolving conjugated polymer solution, filtering the conjugated polymer solution, coating a conductive substrate with the conjugated polymer solution to form a film, heating the conjugated polymer film to obtain a conjugated polymer crystal film which generates fibrous crystal, washing and drying the conjugated polymer crystal film which generates the fibrous crystal to obtain conjugated polymer nanofiber crystal, then, in a process of scanning the conjugated polymer nanofiber crystal by an AFM (Atomic Force Microscope), alternately applying small voltage and big voltage to the probe, and therefore,constructing the pattern on the surface of the conjugated polymer nanofiber crystal. By use of the construction method, on the basis of Joule heating or the combination of Joule heating and thermal oxidation, the scanning probe is used for realizing control and patterning for the conduction performance of the conjugated polymer crystal on a nanoscale, the constructed pattern is free from substancetransfer, and the surface morphology of the material is not changed.
