Abstract

The invention discloses a method for preparing cuprous sulfide / polyethyleneimine / fiberglass composite conductive fiber. The method comprises the steps of conducting surface treatment on fiberglass with vacuum plasmas; immersing the plasma treated fiberglass in a polyethyleneimine aqueous solution, and then conducting rinsing with water and drying to obtain fiberglass with surface modified by polyethyleneimine; placing the fiberglass with surface modified by polyethyleneimine in a copper sulfate pentahydrate aqueous solution, adding a sodium thiosulfate aqueous solution after soaking, taking fiber out after reaction, and conducting rinsing with water and drying to obtain the cuprous sulfide / fiberglass composite conductive fiber. When the method is used for preparing conductive fiberglass, equipment investment is low, operation is easy, reaction conditions are mild, adaptability is high, treatment effect is good, fiber performance loss is low, quality is reliable, and environment pollution can be reduced. The method is suitable for industrial production.

Description

technical field [0001] The invention belongs to the post-treatment field of glass fibers, in particular to a method for preparing a cuprous sulfide / polyethyleneimine / glass fiber composite conductive fiber. Background technique [0002] In recent years, with the rapid development and popularization of computers, telecommunications, microwave ovens, etc., the electromagnetic radiation in the living and working environment of human beings has become increasingly serious. The resulting electromagnetic wave interference has brought many negative effects to the normal operation of electronic equipment and human physical health. influences. In order to prevent electrostatic interference and electromagnetic wave interference, various antistatic and electromagnetic shielding materials have been developed since the middle of the 20th century. In recent decades, the focus of research has shifted more to conductive fibers. The antistatic effect of conductive fibers is more significant ...
