Abstract

The invention belongs to the field of preparation of composite conductive fibers and relates to a preparation method of a polyvinyl alcohol composite conductive fiber. According to the preparation method, firstly, polyvinyl alcohol is used as a base body, copper sulfate and sodium thiosulfate are used as raw materials, nano cuprous sulfide is produced in situ through a chemical reaction in a polyvinyl alcohol aqueous solution, a nano cuprous sulfide / polyvinyl alcohol composite spinning solution is obtained, and the nano cuprous sulfide / polyvinyl alcohol composite conductive fiber with lasting conductivity is prepared from the spinning solution in a wet spinning manner. The traditional polyvinyl alcohol wet spinning technology is adopted, existing requirement is not required to be transformed or replaced, the equipment investment is low, the technological route is simple, the operability is high, and the production efficiency is high. According to the preparation technology of the conductive fiber, the conductive network is formed in the fiber, a conductive layer cannot fall off during usage, the effect of the use environment is avoided, and the conductive function is lasting.

Description

technical field [0001] The invention belongs to the field of composite conductive fiber preparation and relates to a preparation method of polyvinyl alcohol 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 on the normal operation of electronic equipment and human physical health. , In order to prevent electrostatic interference and electromagnetic wave interference, various antistatic and electromagnetic shielding materials have been developed for various purposes 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 significant and durable, and...
