Abstract

The invention discloses a preparation method of a methylated polythiophene electromagnetic material, wherein water is used as a solvent instead of chloroform as the solvent in a polymerization reaction of thiophene in prior art, so that complex processes for treating the organic solvent is avoided, and time is saved and production cost is reduced; meanwhile, with deionized water as the reaction solvent, the method has good safety, is environment-friendly, and is beneficial to industrial production.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a method for preparing a methylated polythiophene electromagnetic 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 materials is better ...
