Statement of the Problem: Rubber has an excellent sealing ability and can be successfully used as sealing elements of different systems. There are no fields of industry where the rubber is not used. But sometimes the use of rubber has limitations due to insufficient strength, resistance to wear and oil, etc. The application of the fillers into rubber mix is one of the usual ways to improve up of physical and mechanical properties of rubbers specifically hardness, tensile straight, modulus. The properties of filled rubbers strongly depend on the interaction between the filler particles and the polymer matrix. There is a close correlation between the structure of filler and the modulus of a rubber product compounded with that filler. But still the reinforcing mechanism of rubber with active fillers is not completely studied. The purpose of this study is to describe the mechanism of rubber reinforcement with the use of atomic force microscopy (AFM). Methodology & Theoretical Orientation: AFM is perfect technique that allows us to see and measure surface structure with unprecedented resolution and accuracy. So, we employed AFM to study the surface properties of the supramolecular structure deformation of rubber composites under uniaxial stretching. Findings: The influence of single-wall carbon nanotubes (SWCNT) on the properties of nitrile butadiene rubber (NBR). It was estimated that a small amount of SWCNT (less than 1 mass. part) into NBR does not lead to a change in the physical and mechanical and basic technical properties. A significant increase in strength characteristics is observed only at 2.5 and 5.0 mass. part of SWCNT. AFM allowed us to visualize of the deformation of the spatial grid structures formed by SWCNT, microcracks formation and to estimate the dependences of the Poisson's ratio and the surface roughness on the degree of uniaxial tension.
