The high‐frequency alternating electrical properties of silver powder and its rubber composites
Source abstract
Abstract
Electromagnetic shielding materials are widely used in alternating electric fields. As a result, the alternating current (AC) conductivity is vital to the electromagnetic shielding effectiveness. In this article, we designed a kind of test method about powder conductive properties and studied AC conductivity of silver powder and the silicon rubber composite, which presented that a sharp peak of impedance would take place in the both systems during the high frequent electric flow. Through the design of the equivalent circuit and the test of the system parameters such as the dielectric constant, this article displayed the impedance model of the silver powder and the silicon rubber composite. The calculated results and the experimental data match very well. POLYM. COMPOS. 37:1122–1127, 2016. © 2014 Society of Plastics Engineers
