摘要

Preparation and characterization of materials absorbing microwave radiation based on the mixture of elastu00c8meros and polu00ecmeros intrinsically conductors ".Invention patent of an elastomeric material which absorbs radiation in the range of driver microwave.This material is based on intrinsically conductive polymers (ICP) and polypyrrole, politiofeno,Polyaniline and its derivatives and ethylene propylene diene elastomer type (EPDM) and nitrile rubber (NBR).The obtaining of the elastomer conductors is carried out by the mixture of mechanical components in internal mixer.Materials are prepared with different reasons mass / mass of elastomer / pic (99 / 1 5 / 95).This mixture is hot pressed or cold and subsequently characterized by measures of radiation absorption at high frequ00b3u00eancias (2 to 20 GHz).The characteristics of the electromagnetic absorption are functions of the concentration of CIP in the matrix, the relationship between mass / mass of PIC / dopant.The thickness of the blanket and the processing conditions (temperature and time).
