Nanocoatings formed by different plasma and chemical methods on the surface of polymeric materials have unique properties. However, the applicability of polymeric materials with nanocoatings under specific temperature and mechanical conditions depends on the physical and mechanical properties of the coating. Determination of the Young's modulus is the problem of primary importance, since it is commonly used to calculate the stress-strain state of structural elements and finished products. Small thickness of nanocoating is the factor that limits the choice of methods for determining the elastic modulus.
The values of the Young's modulus of a carbonized layer formed on a polyurethane substrate were determined under different ion-plasma processing conditions. A method for evaluating the elastic modulus of a carbonized nanolayer formed by plasma processing of a polymer surface was developed based on the results of uniaxial tensile tests. This was a pioneering work, which demonstrated the possibility of using uniaxial tensile tests for determining the elastic modulus of the nanolayer formed on a soft substrate
