Complex microscopy investigation of special purpose elastomers

摘要

New types of elastomers (rubbers) for use in extremal conditions of north were proposed and investigated. New type of filler-carbon nanotubes were added to a basic elastomer composition in different proportions. Surface parameters of the samples were studied before and after tribological tests. Electron microscopy was used to study the relief and elemental composition of the surface and section (after the tests). Probe microscopy made it possible to investigate the adhesion and elastic properties of the surface at the nanoscale. Unmodified samples and samples with a small amount of nanotubes are remarkably changing in topography and elemental composition after tribological tests: the amount of carbon increased, while amounts of nitrogen, sulphur, and zinc decreased. Modification of the basic composition by nanotubes significantly changes the properties of rubber. Cross-sections showed that composition of the depth became more stable. Modified samples have a great adhesion strength and Young's modulus.
