The main achievements of Department:
New theoretical concepts considering interphase phenomena in composite polymers were developed. The relation between the extreme changes of rheological behavior of polymer blends and their thermodynamic characteristics was established in detail for systems polymer-polymer.
The thermodynamic theory of polymer adhesion to solids and the theory of polymer adsorption from semi-dilute and concentrated solutions were created.
Mechanism of fillers reinforcement in composite polymer materials was formulated on the basis of theoretical conceptions about the polymer behavior in the thin surface layers at the interface with solids.
Physical-chemical fundamentals of creation of filled and reinforced plastics were developed: the general concept of formation of their properties was formulated taking into consideration the decisive influence of the interphase layers on the physical, chemical and mechanical properties of the filled polymers.
The scientific principles of creation of functional phase structure of polymeric materials by means of chemical regulation of interphase interactions and phase transformations in complicated heterogeneous systems.
On the basis of the fundamental investigations were developed:
- High-performance damping materials with wide range of operating temperatures and damping frequencies to prevent vibrations of structures, mechanisms and devices.
- Wear-resisting composite "Armilon" for manufacturing the up-to-date electronic components, cars' frames, and constructs for operation under alternating loading.
- Polymeric frictional composition "Polyfrim" for manufacturing the thermo-, water- and oil-resistant frictional materials (including brake blocks for the automobiles).
- Termostable binding agents for manufacturing the heating elements with high temperature of operation (up to 400 Ñ).
- Technology of recycling of packing materials wastes, namely paper-cardboard raw materials and polymeric films.
- Glue solvent free compounds and sealing materials:
- Glue composition Kl-P-7 for use in solar batteries of spacecrafts. This composition is stable for thermocycling under the conditions of space vacuum in temperature range -150...+100 Ñ and is stable to impact of accelerated electrons;
- Elastic optically-transparent glue-compound Kl-OP, which is stable to the impact of UV-radiation and radioactive emanation, and is used for protection of the optical elements of spacecrafts from the influence of the outer space.
The above-stated projects are offered for realization to the interested enterprises and businessmen in the form of mutually beneficial cooperation.
