On the interaction between rubber based composite materials and microwave radiations

Summary form only given. The objectives of the present paper are: on the basis of a better understanding of the mechanisms and level of interaction between microwaves (as a technological hazard resulting from technological development) and solid materials (consisting of a rubber matrix solid dispersion system) to develop improved coatings for protection. The investigations in the present paper are focused on the clarification of the role of the rubber matrix and fillers´ crystallochemical nature and crystallographical structure on the level and mechanisms of interaction. In the paper are included the following discussions: (1) changes in the structure and microwave properties of rubber composite materials when in their compositions simultaneously present very different in magnetic functional fillers-isotropic and anisotropic, including the case of their combination with nonmagnetic ones; (2) the influence of hard magnetic high coercive force fillers on the frequency spectra of permeability and permittivity real and imaginary parts; (3) the influence of the fillers´ nature on their distribution in the rubber matrix
