Abstract

The invention discloses a polyethylenedioxythiophene nanotube array and its preparation method and application. The array is polyethylenedioxythiophene with neatly arranged nanotubes arranged in an array. At least one end of the nanotube is Transparent, the array is insoluble in water, transparent, and conductive. The preparation method includes the following steps in sequence: secondary anodic oxidation to obtain independently separated TiO2 nanotube arrays; using the independently separated TiO2 nanotube arrays as anodes and platinum wires as cathodes, performing constant potential or constant current electropolymerization to obtain selective in The TiO2 nanotube array tube and the tube space are filled with polyethylenedioxythiophene composite material, and the TiO2 nanotube array is removed with hydrofluoric acid to obtain polyethylenedioxythiophene with neatly ordered nanotubes arranged in an array. The composite material can be used as a transparent electrode material, and can be applied in the fields of organic thin-film solar cells, antistatic coatings, organic optoelectronics, electrochromism, and solid electrolytic capacitors.

Description

technical field

[0001] The invention belongs to the field of electrochemical inorganic / organic composite materials, in particular to a polyethylene dioxythiophene nanotube array. Background technique

[0002] Since Shirakawa discovered that polyacetylene has high electrical conductivity, the field of conducting polymers has aroused widespread interest among scientists.

[0003] In the late 1980s, German scientists at Bayer first studied a new type of thiophene derivative - polyethylene dioxythiophene, or PEDOT. The original purpose was to obtain an antistatic coating material with good environmental stability, but subsequent research showed that this polymer not only has good environmental stability, but also has high conductivity, and has been commercialized in many fields abroad. PEDOT, like conductive polypyrrole and conductive polyaniline, can be polymerized in situ by chemical oxidation to prepare the material for the cathode of a solid electrolytic capacitor, and its ...
