Description

technical field [0001] The invention relates to a conductive polymer oligomer and its application, belonging to the technical field of conductive polymer preparation. Background technique [0002] Conductive polymers, also known as conductive polymers, are a class of polymer materials with large π-conjugated molecular skeletons that can be converted from insulators to conductors by chemical or electrochemical doping. Common conductive polymers are polypyrrole, polyaniline, polythiophene and polyacetylene. [0003] Polypyrrole, polyaniline and polythiophene obtained by chemical or electrochemical oxidation polymerization with five-membered aromatic heterocyclic molecules (pyrrole, aniline, thiophene) as monomers have the advantages of easy synthesis, high electrical conductivity, environmental friendliness and biological The advantages of compatibility (J. Phys. Chem. C, 2009, 113, 21586-21595.), in energy storage and conversion, microwave absorption, electrostatic protectio...

Problems solved by technology

Both methods have their own advantages and disadvantages: the advantage of the former is that the monomer polymerization reaction time is short, it is easy to realize the controlled synthesis of particle morphology, and the conductivity of the product is better; the disadvantage is that the product is difficult to dissolve in conventional organic solvents, and it is not easy to obtain Conductive polymer film and solution post-treatment are cumbersome; the advantage of the latter is that there is no solvent in the polymerization process of the monomer, and a conductive polymer film can be deposited on the surface of any substrate without the need for conductive polymer dissolution. ; The disadvantage is that before coating the surface of the substrate, it is necessary to coat a layer of oxidant film. After the reaction, the oxidant needs to be removed by cleaning.

However, using oxygen or air as an oxidant to synthesize polypyrrole or pyrrole oligomers by chemical vapor deposition has not been reported in the literature so far.
