Аннотация: The possibilities of creating new types of frost-resistant rubbers by using carbon nanotubes as a filler (modifier) for an elastomeric base (epichlorohydrin rubber) are studied. Samples with a nanotube content of 1 and 10% and the initial unmodified sample are compared. The initial samples and the samples after tribological tests are studied by the method of scanning electron microscopy (with elemental analysis). The method of scanning probe microscopy is used to study the surface topography and the physicomechanical properties (modulus of elasticity and adhesion). The addition of carbon nanotubes to the elastomer is shown to stabilize its composition and to result in structuring of the elastomeric base. The investigation of sample slices prepared after tribological testing makes it possible to distinguish several areas: thin “surface” (a thickness of 10–15 μm) and “near-surface” layers. Strong element redistribution is recorded, i.e., the concentration of sulfur and zinc increases significantly on the surface. It is shown that during tribological tests, the main changes occur mostly in the surface layer, while the near-surface layer does not transform so considerably. It is established that the addition of carbon nanotubes leads to an increase in the modulus of elasticity in the near-surface layers.
