Problems solved by technology

[0007] Graphene with a complete structure is composed of stable benzene six-membered rings, its surface is inert, and the interaction force between it and the polymer is small, while there is a strong van der Waals force between the graphene sheets, which is easy to aggregate and difficult to Uniform dispersion in the polymer matrix, which seriously affects the research and application of graphene in polymer modification

Abstract

The invention discloses a preparation method of quaternary ammonium salt modified polythiophene intercalation graphene. After polythiophene is composited with other organic and inorganic materials, not only can electrical conducting properties of polythiophene be improved, but also multiple new properties can be shown, so that polythiophene can be applied to multiple fields such as electric conductors, photoelectric materials, electromagnetic shielding materials, microwave absorption materials, metal anticorrosive coatings and the like.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method of quaternary ammonium salt modified polythiophene intercalation graphene. 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 ...
