Abstract

The invention relates to a preparation method of nano-structure polyaniline. The method comprises the following steps: dissolving an aniline monomer and a monomer initiator into an alkali liquor respectively and carrying out mixing and reacting to obtain an aniline oligomer; adding a strong acid to the aniline oligomer, adjusting the pH to 0-7, and then sequentially adding acid-doped solutions of the aniline monomer and the monomer initiator, and reacting in an ice-water bath for 0.5-24 hours; and carrying out washing, suction filtration and drying to obtain the nano-structure polyaniline. By the method provided by the invention, the intermediate processing link of the aniline oligomer is avoided; a template and other auxiliary equipment are not needed; the overall reaction is finished in a water phase; the operation is simple and convenient; the controllability is high; and the method is suitable for large-scale production. The prepared polyaniline can have wide application potential in the fields of an energy storage material, a sensing material, a wave-absorbing material, an adsorption material, a nano additive and the like.

Description

technical field

[0001] The invention belongs to the field of polyaniline preparation, in particular to a preparation method of nanostructure polyaniline. Background technique

[0002] Polyaniline is a very important conductive polymer material, which has the advantages of easy availability of raw materials, low price, diverse structures and environmental friendliness. By controlling different doping levels, polyaniline can realize the transformation from conductor-semiconductor-insulator. Nanostructured polyaniline has a high specific surface area, which can greatly increase the contact area between polyaniline and other materials, and endow polyaniline materials with new characteristics. In addition, polyaniline with different nanostructures, such as nanofibers, nanotubes, nanowires, nanosheets, sea urchins or petals, etc., can bring some new structural properties, which broaden the application of polyaniline materials in supercapacitors, electrical Applications in cataly...
