Description

technical field [0001] The invention belongs to the field of composite conductive fiber preparation, and in particular relates to a preparation method of nanometer cuprous iodide / 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 conductiv...
