Abstract

The invention provides a composite and conductive polyimide / nickel fiber and a preparation method thereof and belongs to the field of electromagnetic-shielding and conductive fiber. Polyimide fiber is used as basic fiber, the surface of the polyimide fiber is supported with an ultra-thin metal layer through a surface modified ion exchange technique, then uniform precipitation of the metal nickel layer is conducted on the surface of the fiber by adopting a traditional chemical plating method, and accordingly a perfect and compact high-conductive metal nickel layer is obtained. Efficient preparation of the polyimide / nickel fiber having excellent surface metal luster, good interface caking property, high conductivity and controllable nickel layer thickness. The implementing process is simple, processizing is easy, and an application prospect is good.

Description

technical field

[0001] The invention belongs to the field of electromagnetic shielding conductive fibers, in particular to a polyimide / nickel composite conductive fiber and its preparation technology. Background technique

[0002] Conductive fiber refers to the standard state (20 ℃, relative humidity 65%), the conductivity of 10 -7 Fibers above S / cm. Conductive fibers have multiple functions such as conduction, antistatic, reflection and absorption of electromagnetic waves, and sensing. They are widely used in antistatic textiles in the electronics industry, conductivity sensors, electric heating bandages in the medical industry, electromagnetic wave shielding textiles, and electromagnetic in the aerospace industry. Shielding material, stealth material. World-renowned chemical fiber companies such as DuPont, Monsanto, BASF, Solutia in the United States, Epico in the United Kingdom, Kanebo, Teijin, Unitika, Kuraray and other companies are competing to launch various conduct...
