Influence of mechanical loads on the structure of a carbonized layer of polyurethane samples.

The aim of the paper is to study the effect of various types of mechanical loads on the state of carbonized layers on the surface of polyurethane samples using atomic force microscopy. We study the ability of the carbon layer to maintain its structural integrity as a result of large deformations, as well as the possibility of cracking and delamination in the case of insufficient elasticity and weak adhesion of this layer to the substrate of the raw material. Particular attention is paid to the study of the ability (or inability) of the carbon layer to maintain the listed operational properties in the temperature range relevant to the human body. The results of the study are actual in the search for optimal parameters for the manufacture and ion-plasma processing of samples capable of maintaining the integrity of the surface layer without destruction and the appearance of defects.
