Description

technical field

[0001] The invention relates to a method for preparing polyaniline with high conductivity in a magnetic field environment. Background technique

[0002] Polyaniline has the advantages of easy to obtain raw materials, simple synthesis, fast and reversible redox reaction, high density charge storage, good optical, electrochemical properties and chemical stability, etc., and is considered to be the most promising in practice. widely used conductive polymer materials. Therefore, it has become a research hotspot in recent years to effectively improve the conductivity, corrosion resistance and processability of polyaniline.

[0003] Relevant studies have shown that: the magnetic field acting on organic macromolecules, particles or organisms will produce certain physical and chemical effects, the magnetic field can change the orientation of molecules, paramagnetic molecules can be arranged along the direction of the magnetic field, and the orientation of the conjug...
