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...

Problems solved by technology

However, conventional processing methods for the preparation of polymer-based inorganic filler composites, such as twin-roll milling, screw extrusion, melt mixing, solution mixing, etc., cannot be used to prepare polymer-based inorganic nanocomposites in general, because these conventional methods start from Essentially the scale of dispersion and mixing is above hundreds of nanometers

Due to their extremely high surface energy, inorganic nanoparticles have a strong tendency to agglomerate. When they are mixed with polymers, they encounter heat and other effects, which destroys their original dispersed equilibrium state, and often results in the agglomeration of nanoparticles into hundreds of Composite materials at the nanometer or even micrometer scale, thus losing the unique functions and effects of nanoparticles
