Novel Composite Shielding Materials for Supression of Microwave Radiation

In this paper we describe a novel approach for shielding composite materials synthesis that is based on formation of micro-and nano-sized volumes of microwave absorbing media in fiber matrix. Such method allows fixation of liquid and solid phases in flexible basis and creation of materials with "human-body-like" characteristics. The solid inclusions are formed using oxidation-reduction and surface absorption reactions in aqueous solutions while liquid volumes are created by impregnation of porous fiber matrix. This paper presents method for synthesis of porous fiber matrix and composite material. We studied the electrical properties of fiber matrixes containing different fillers. Study of microwave characteristics of the shielding constructions were carried out in wide frequency range.
