Preparation method of cuprous sulfide/carboxylated chitosan/glass fiber composite conductive fiber

Abstract

The invention provides a preparation method of cuprous sulfide / carboxylation chitosan / glass fiber composite conductive fiber. An alkali-free glass fiber is immersed in an aqueous hydrochloric acid solution, and is sufficiently rinsed with water and dried to obtain a hydroxylated glass fiber after soaking; the hydroxylated glass fiber is immersed in a carboxylation chitosan aqueous solution, and then is taken out after soaking and the taken hydroxylated glass fiber is immersed into a glutaraldehyde solution, is taken out and is sufficiently rinsed with water and dried to obtain carboxylation chitosan surface modified glass fiber; the carboxylation chitosan surface modified glass fiber is put into a copper sulfate pentahydrate aqueous solution, and is added into a sodium thiosulfate aqueous solution after soaking, then the soaked carboxylation chitosan surface modified glass fiber is taken out and rinsed with water and dried after reaction to obtain the cuprous sulfide / carboxylation chitosan / glass fiber composite conductive fiber. The process is used for preparing the conductive glass fiber, the equipment investment expense is low, the operation is simple, the reaction condition is mild, the applicability is strong, the treatment effect is good, the fiber performance loss is low, the fiber quality is reliable, the environment pollution is alleviated and the method is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of preparation of composite conductive fibers, in particular to a preparation method of cuprous sulfide / carboxylated chitosan / glass fiber composite conductive fibers. 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 i...
