Problems solved by technology

However, the research on the assembly process of these nanostructures at the air / liquid interface is still in its infancy, and the dynamic assembly mechanism and process of nanostructures at the air / liquid interface require in-depth and systematic research.
[0007] Judging from the current research, the research on PEDOT ordered nano-films has made some progress, but there are still many problems, the most important of which is the stable and reliable assembly of ordered nano-structures, which is very important for the device after the device is prepared. Performance has a very heavy impact

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a method for preparing a conductive polymer ordered micro / nano structure array. Background technique [0002] In recent years, conductive polymer materials with regular morphology (such as balls, wires, ribbons, tubes, etc.) in the micro- and nano-scale range have become a research hotspot for scientists from all over the world. After these novel conductive polymer nanostructures interact with certain media in the atmosphere, due to the large specific surface area and excellent surface conditions of the material, the gas molecules can be adsorbed / desorbed on the surface of the sensitive material quickly, making the gas sensor With the characteristics of fast response, high selectivity, and room temperature operation, it is a research hotspot for the next generation of gas sensor sensitive materials. However, at present, this conductive polymer material is basically in a disorder...
