Abstract

On the basis of mixes of phenolformaldehide and epoxy resins at presence of some silicon organic compounds and fiber glasses annealed in vacuum and hydrogen media the new conductive monolithic materials have been created. There were investigated the conductive, magnetic and some other properties of these materials. It is established experimentally that the obtained products are characterized by semiconductive properties, the level of conductivity and conductive type of which are regulated by selection of technological methods. The density and mobility of carriers increase at increasing of annealing temperature up to definite levels. The temperature dependence of the electrical conductivity and charge mobility describe by Mott formulas. The magnetic properties of the annealed materials are investigated by ESR method. It is established that at annealing free radicals and other paramagnetic centers are formed. On the basis of obtained results it is proposed that formation of conducting clasters the charge transport between them provides by mechanism of charge jumping with alternative longevity of the jump.
