Abstract

The invention relates to a functionalized conductive polymer film supported by a substrate and a preparation method thereof. The preparation method is as follows: firstly, an oxidant film is formed on the surface of the substrate by a spin coating method, and then the functionalized monomer is used as a raw material to carry out a chemical vapor phase A functionalized conductive polymer film is formed on its surface by deposition polymerization to obtain a functionalized conductive polymer film supported by a substrate, and the functionalized monomer is functionalized 3,4-ethylenedioxythiophene functionalized aniline or functionalized pyrrole wherein, R A substrate-supported functionalized conductive polymer film for ‑OH, ‑COOH or prepared, mainly composed of a substrate and a functionalized conductive polymer film deposited on its surface, the substrate is a silicon dioxide sheet, a glass sheet or a single Crystalline silicon wafers, functionalized conductive polymers are polymerized from functionalized monomers. The method of the invention is simple and easy; the prepared functional conductive polymer film supported by the base has good contact with the base and has excellent electrical conductivity.

Description

technical field [0001] The invention belongs to the technical field of conductive polymer materials, and relates to a substrate-supported functionalized conductive polymer film and a preparation method thereof. Background technique [0002] Polymers are generally insulating materials, but in 1970, researchers first discovered that polyacetylene doped with iodine or bromine has the conductive properties of metals, which changed the concept that polymers cannot be used as conductive materials. In 1980, conductive polymers polypyrrole, polythiophene, and polyaniline were also discovered. The remarkable feature of conductive polymers is that there are a large number of conjugated π-electron systems in the molecule. When the conjugated structure is large enough, it can provide carriers. These carriers can act along the polymer chain under the action of an electric field. Directed movement, which makes the polymer conductive. [0003] The emergence of this new type of material, ...
