EMI SHIELDING MATERIALS, FIBERS THEREFOR AND METHOD FOR THEIR PREPARATION

摘要

EMI shielding materials in form of plates, panels, and fabrics and methods for their preparation and for preparing highly filled ferromagnetic fibers therefor are described. In the method the ferromagnetic filler is treated in an ultrasonic dispenser or a ball mill in the presence of a binder polymer and then the fiber is made by wet spinning from a dispersion containing solution or gel of the polymer.
