Embodiment 1

[0022] A preparation method of polythiophene conductive polymer nanowires, the steps are as follows:

[0023] (1) Prepare the template solution: prepare a hydroxyethyl cellulose solution with a concentration of 0.01 wt % (dissolve hydroxyethyl cellulose in a buffer solution pH=6.86), and let it stand for 12 h.

[0024] (2) Prepare the template by pulling the template method: Slowly and vertically immerse the cleaned conductive glass piece in 0.01 wt % hydroxyethyl cellulose solution for 5 minutes. The conductive glass sheet (ITO) is slowly pulled out of the solution by a pulling method to obtain a conductive glass sheet with template molecules attached, that is, the template prepared by the pulling template method.

[0025] (3) Slowly immerse the template glass piece in the electrolyte solution (boron trifluoride ether BFEE / trifluoroacetic acid TFA mixed electrolyte (volume ratio 3:1)) in which the monomer 3-thiophene acetate is dissolved, the monomer concentration is 0.1mol×...

Description

technical field [0001] The invention relates to a method for preparing polythiophene conductive polymer nanowires, in particular to a method for preparing poly(3-acetic acid)thiophene nanowires by a pulling template method. Background technique [0002] Conductive polymer material is a new type of functional polymer material developed rapidly in recent years. Due to its unique structure and physical and chemical properties, it has been widely used and has a good development prospect. Doped polyethylene is the earliest conductive polymer discovered, and many new varieties have been discovered so far, such as polypyrrole, polyphenylene sulfide, polyphthalocyanine compounds, polythiophene and its derivatives, polyaniline and other high-conductivity polymers. molecular material. Among them, the conductivity and density of polythiophene films have the best values, because polythiophene derivatives have higher conductivity than polythiophene itself, and poly(3-acetic acid)thioph...
