1. Tribological properties of solid polymer systems.

2. Degradation of solid fullerene-polymer systems.

3. Structure and mechanical properties of solid polymer systems at different scale levels.

4. Structure and properties of fullerene and fullerene-polymer solutions.



1.Solid polymer films, fibers and composites, in particular on the base of superplastics,

with fullerene-containing additives (fullerenes and fullerene soots)

2. Solid polymer films with covalent and non-covalent bonded fullerenes

3. Fullerene and fullerene-polymer solutions



The measurements of friction coefficient, volume wear and other tribotechnical parameters are used for study of tribological properties at different pressures from a few units to hundreds of MPa. For study of materials' structure are used the methods of others laboratories in collaboration: SAXS, WAXS, ESCA, TEM, SEM, AFM, different modifications of mass-spectrometry, DSC, TGA, machines for mechanical tests and relaxation, etc.

1. Tribological properties of fullerene-containing systems.

Different parameters of tribological properties are determined at variation of type of contact of counterbodies, contact pressures, rate of sliding, etc. (Fig. 1).


Fig. 1. Determined tribological parameters. Note: Q is the probability of transformation of a contact spot into a wear particle by the relative shift of counterbodies on the diameter of the contact spot; HB is Brinnel's hardness, Pn is contact pressure; d/g is relation of diameter to height of wear particle.













Mechanism of action of fullerene-containing additives on antifriction, antiwear, and antiscoring properties of liquid mineral industrial oil and greases is investigated. Fullerenes initiates the formation of tribopolymer film on the friction surfaces at the sliding friction (Fig. 2).

2. Degradation of solid fullerene-polymer systems.

It was found a very strong influence of C60 on the covalently attached to it polymer chains: for example, the temperature of start or maximum rate of degradation of atactic polystyrene decreases more than 100 C (Fig. 4a).

In the case of mixtures with polymers fullerene C60 plays a role of a trap of free radicals that provides an increase of thermal stability from the side of low temperatures as for atactic poly(methyl methacrylate) (Fig. 4b).

At the thermo-oxidative degradation of a free-radical poly(methyl methacrylate) a small quantities of C60 in the polymer blend system results in replacement of oxygen by a fullerene and transfer of degradation, oxidation, and heat generation to higher temperatures.

3. Structure and mechanical properties of solid polymer systems at different scale levels.

A new concept was proposed for supermolecular organization and deformation mechanisms of semicrystalline polymers. This concept is based on the idea of existence of critical shear angle of crystallites. From this point of view are interpreted structure changes at all points of deformation curves. Some new ideas were developed about the mobility of supermolecular units (such as fibrils) in oriented semicrystalline polymers. A simple X-ray technique was proposed for determination of the easiest slip planes in polymer crystallites (Fig. 5).

4. Structure and properties of fullerene and fullerene-polymer solutions


On the base of SAXS, WAXS, densimetry, and DSC data it was proposed the model of supermolecular organization of fullerene C60 solutions and their changes with concentrations in aromatic solvents (Fig. 7).

Fig. 7. The scheme of changes of supermolecular structure of C60 solution (on example of p-xylene), explaining the character of SAXS intensity change. Initial solution (a); a solution at small concentration of C60 (b); a solution at critical concentration Cstr (c); a solution at concentration above critical (d). 1 non-disturbed solvent; 2, 3 the greatest and others thermal density fluctuations, respectively; 4 molecules of C60; 5 "liophobic" shell around the molecules of C60; 6 "liophilic" shell and structured solvent with the same elevated density; 7, 8 suppressed thermal fluctuations with the elevated density. For toluene solutions the single molecules of C60 must be changed on their aggregates.

A model of the supramolecular benzene structure and its changes induced by the introduction of fullerenes into benzene is proposed based on the complex consideration of previously calculated and experimental data (Fig. 8).

Fig. 8. Possible benzene configurations in a block: (a) PD1 configuration with displacement toward the same side; (b) PD2 configuration with periodically alternating displacements toward both sides; (c) configuration near a fullerene molecule; (d) PD configuration near a fullerene molecule, located so as to form the configuration with a six-membered fullerene ring; and (e) PD2 configuration near a fullerene molecule.
