In this study, we used different proportions of conductive nano-materials added to the acrylic, nylon, polyester polymer solution for electrospinning to produce films, SEM observation of surface changes and fiber diameter and testing of electromagnetic wave absorber of adding different proportions of the conductive nano-materials, to comparison of effects of electromagnetic waves. In this work, different voltages on the electro-spinning fiber diameter is little effect, but the higher the concentration of the solution the biger the fiber diameter,and we add carbon nanotubes polymer solution the fiber diameter smaller, more film the higher the value of the absorption of electromagnetic waves.
