Problems solved by technology

When thiophene is polymerized in a chloroform solvent, it is often necessary to evaporate the chloroform or dispose of it by other means, which increases the time and cost of the reaction and is unfavorable for industrialization; while by electrochemical polymerization, it is necessary to seek a suitable solvent (and The amount is relatively large), and there are too many variable factors, it is difficult to guarantee the quality of polythiophene, and the industrialization is also limited;
[0006] The compatibility between inorganic filler and polythiophene is relatively poor, and the stability of the finished product is low. Therefore, the purpose of the present invention is to endow the composite material with new functions on the basis of improving the stability and compatibility of polythiophene and inorganic filler, so as to enhance its performance in different domain applicability

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method of a quaternary ammonium salt-loaded magnetic polythiophene material. Background technique [0002] Conductive polymers are a class of polymers with conjugated structures. Chemical, electrochemical or ion doping can make the conductivity level of the polymer from the insulating level to the metal level. It is used in capacitors, energy, metal anti-corrosion and biosensors. It has a good application prospect; [0003] Polythiophene has been paid attention to by researchers because of its good optical, electrical and environmental stability. It is compounded with inorganic nanomaterials to form organic-inorganic nanocomposites, not only because of the introduction of inorganic substances to improve its original performance, but also because of the nano effect and the synergy between polythiophene and inorganic substances, the performance of composite mater...
