Gorshunov O. Thermophysical properties of modified epoxy polymers

This investigation dedicated to study of metal filler and compound preparation regime influence on DGEBA-based epoxy polymer structure formation, thermal-physical, mechanical, physico-chemical, electric properties, resistance to corrosive medium, relaxation processes (particularly conditioned by annealing). Epoxy polymer - metal filler system model developed. Proposed model bases on generalized structure parameter - specific free volume and taking in account absorption and orientation interfaces. Dependency dCp/dT shape analysis method proposed. Method allows obtaining epoxy polymer glass transition parameters. It was shown, that glass transition in epoxy polymers consist of two parts: glass transition in globules and glass transition in interglobula space. On the basis of filled systems calorimetric and mechanical investigations, substantiated that volume relaxation driven by interface structure. First time shown, that volume relaxation in lattice polymers related with meta-stable structure formation.
