Problems solved by technology

[0003] However, the stability and mechanical properties of conductive polypyrrole materials are poor. In order to improve and enhance the performance of polypyrrole, a large number of researchers have focused on the composite of polypyrrole and other materials. In recent years, the composite of carbon materials such as carbon nanotubes has been widely used. The research results show that the combination with carbon nanotubes can greatly improve the performance of supercapacitors. However, carbon nanotubes have disadvantages such as high cost and low specific capacitance. Therefore, how to improve the stability, strength and mechanical properties of polypyrrole is the current research the key of

Abstract

The invention discloses a polypyrrole conduction fiber, which is prepared from the following raw materials in parts by weight: 2 to 4 parts of oleic acid, 1 to 2 parts of ammonium molybdate, 0.7 to 1part of aminopropyltriethoxysilane, 20 to 30 parts of triazole monomers, 0.7 to 1 part of dibenzoyl peroxide, 0.6 to 1 part of 2,6-di-tert-butyl paracresol, 4 to 6 parts of blanc fixe, 70 to 80 partsof polyacrylonitrile and 5 to 7 parts of isopropanol. The triazole monomers are polymerized in an alkamine solution; the obtained aminopyrrole solution is mixed with oleic acid treated filling materials; through the reaction between amino groups and oleic acid, the effective dissolution of the polypyrrole and the filling materials can be realized, so that the mechanical stability and the conduction stability of a finished product material are improved.

Description

technical field [0001] The invention belongs to the field of fibers, in particular to a polypyrrole conductive fiber. Background technique [0002] Polypyrrole is a common black, insoluble, infusible, and conductive polymer. Polypyrrole is usually obtained by oxidative polymerization of pyrrole monomers. Electrochemical anodic oxidation of pyrrole is also an effective means of preparing polypyrrole; polypyrrole can be used in biology, ion detection, ultra- Capacitor and antistatic materials, modified electrodes for photoelectrochemical cells, and electrode materials for storage batteries. In addition, it can also be used as electromagnetic shielding material and gas separation membrane material, used in electrolytic capacitors, electrocatalysis, conductive polymer composite materials, etc., and has a wide range of applications, and has attracted people's attention since it was discovered; [0003] However, the stability and mechanical properties of conductive polypyrrole ma...
