Investigation of the dielectric properties and defectoscopy of nanocomposites based on silica and polymers reinforced with carbon nanotubes

This work presents the results of experimental studies of the properties of nanocomposites based on silica and polypropylene reinforced with carbon nanotubes by dielectric relaxation and positron annihilation spectroscopy. On the basis of these results the technique of diagnosis and control of the investigated materials are proposed. This work was supported by the project of the Ministry of Education of Russian Federation №3635 "Investigation of the nanocomposites properties at controlled modification of the structure by reinforcement with carbon nanotubes".
