Abstract

The invention belongs to the field of chemical technologies, and particularly relates to a polythiophene / mixed valence metal oxide collaborative conductive slurry and a preparation method of the polythiophene / mixed valence metal oxide collaborative conductive slurry. The polythiophene / mixed valence metal oxide collaborative conductive slurry is composed of film forming matter, conductive filler, coupling agents, auxiliaries and organic solvents. The novel conductive slurry prepared through the preparation method has the advantages of being good in conduction performance, small in density, good in mechanical performance after a film is formed and the like, and the formed conductive film has the advantages of being durable and stable in conduction performance, fine and smooth, resistant to abrasion, high in mechanical impact resistance and the like. In order to enable the conductive filler to be better scattered in the conductive slurry to form a conductive network, a proper amount of conductive coupling agents are further added to the system. The requirement for the conduction performance of the conductive slurry is met by regulating the addition amount of the conductive filler. The conductive filler is composed of polythiophene and mixed valence tungsten and molybdenum metal oxide to form collaborative conductive filler, and the mixed valence tungsten and molybdenum metal oxide conductive materials can effectively improve the mechanical scratching resistance and abrasion resistance of the conductive film formed by the conductive slurry. According to the conductive slurry, when the thickness of the conductive film is 0.1 mm, the surface resistance of the conductive film is only 0.4-8*10-2 omega / cm.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a polythiophene / mixed-valence metal oxide synergistic conductive paste and a preparation method thereof. The conductive paste has good electrical conductivity and oxidation resistance, and has good mechanical properties after the paste is formed into a film, and can be widely used in many fields such as antistatic, electric conduction, and electromagnetic shielding. Background technique [0002] Conductive paste refers to a type of functional paste that is coated on a non-conductive substrate to enable it to conduct current and eliminate the ability to accumulate static charges. Conductive paste often has the advantages of convenient construction, simple production equipment, and wide application range. Because the conductive paste has a very broad application prospect in the fields of electronics, construction and aerospace, it is favored by the industry. ...
