Abstract

The invention relates to a preparation method of a solution-dispersible polypyrrole copolymer. The method comprises the following steps: mixing a soluble polymer, an initiator and a pyrrole monomer under an air condition, and carrying out irradiation treatment by utilizing high-energy rays to obtain the polypyrrole copolymer. Compared with the prior art, the raw materials, the pyrrole monomer, the soluble polymer, the initiator and the like used in the method are commercially available reagents easy to obtain, special treatment is not needed, the reaction condition is mild and easy to control, one-step completion is achieved, and the method has the advantages of being easy and convenient to operate, capable of saving energy consumption, environmentally friendly, wide in application range and the like; and the polypyrrole copolymer prepared by the method can be stably dispersed in water or most of organic solvents, the defect that polypyrrole is insoluble and non-meltable is overcome, and the polypyrrole material is endowed with good processability.

Description

technical field

[0001] The invention relates to the technical field of organic materials, in particular to a preparation method of a dispersible polypyrrole copolymer. Background technique

[0002] Conductive polymers have become the focus of material science research since their discovery, and are widely used in fields such as electromagnetic shielding, energy, optoelectronic devices, and metal anticorrosion (Chem.Soc.Rev., 2009, 38, 2149). Polypyrrole (polypyrrole, abbreviated as PPy), also known as pyrrole black, is a kind of conductive polymer widely studied at present. It is obtained by redox polymerization of pyrrole monomer. Advantages (Polymers, 2016, 8, 373; ACSnano, 2013, 7, 10139). However, polypyrrole itself is insoluble and difficult to process, which greatly limits the wide application of polypyrrole (React. Funct. Polym., 2001, 47, 125). Therefore, modifying the molecular structure of modified polypyrrole, endowing it with dispersibility in various solvents,...
