Abstract

The invention discloses a polyethylenedioxythiophene nanotube array and a film of independent standing nanowires in the tube and its preparation method and application. The film is polyethylenedioxythiophene with orderly nanopores arranged in an array , and there are independent standing polyethylenedioxythiophene nanowires in the nanopore, and the film is transparent and insoluble in water. 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 TiO2 nanotube arrays. The inner and outer spaces of the tube array tube are filled with a composite material of polyethylene dioxythiophene, and the TiO2 nanotube array is removed by hydrofluoric acid to obtain polyethylene dioxythiophene with orderly nanopores 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 present invention belongs to the field of electrochemical inorganic / organic composite materials, and especially involves a poly -B -pipe nano tube array and an independent nano -wire film in the tube. Background technique [0002] Since Shirakawa discovered that polyetle has a high conductivity, the field of conductive polymer has attracted widespread interest in scientists. [0003] In the late 1980s, German Bayer scientists first researched the new type of pneumophyte derivatives -Juli Bybolo, which is PEDOT.The initial purpose was to obtain good environmental stability anti -static coating materials, but subsequent research showed that this polymer not only had good environmental stability, but also had high electrical conductivity. It has been applied in many aspects of commercialization abroad.Pedot, like electrical polypyra, conductive polyiline, can adopt a chemical oxidation method in situ polymerization, which is made of solid electrolytic capa...
