This study will assist in expanding the knowledge base of elastomer compatibility with hydrogen and therefore contribute significantly to the selection and development of polymer materials deploying hydrogen as a future energy carrier.

Furthermore, aging experiments were conducted for 7 days under static conditions in 100 MPa hydrogen and the physical and mechanical properties of the rubber materials were examined before and after hydrogen exposure. Fretting tests revealed that the wear of these compounds is significantly affected by the hydrogen environment compared to air, especially with NBR grades. After aging experiment, the friction response of HNBR grades is characterized by increased adhesion due to elastic deformation, leading to partial slip.

Photooxidative degradation of polymer leads to deterioration of physical and mechanical properties, which affect its tribological behavior significantly. Unfilled TPUs lose their anti-slip properties.
