Abstract :
Nano-Ag/polyacrylamide (PAM) composite can be prepared through radiation polymerization. The structure of the composite is determined by XRD and TEM. The composite is powdered to 45 μm and then mixed with EVA evenly. The resistivity (ρv), and breakdown electric-field intensity (Eb) of this kind of EVA compound substance is measured at room temperature and at cryogenic temperature. The abnormal dielectric behavior of nano-Ag/PAM composite is discussed. The result shows that the resistivity and electric strength of EVA are improved apparently by adding nano-Ag.
