TY - CONF A1 - Theiler, GĂ©raldine A1 - Gradt, Thomas T1 - Tribology of polymer materials in cryogenic hydrogen and methane N2 - The development of hydrogen technologies is a key strategy to reduce greenhouse gas emission worldwide. Power-to-Gas is a challenging solution, in which hydrogen and methane can be used in mobility, industry, heat supply and electriity generation applications. This presentation deals with the tribological behaviour of polymer materials in hydrogen and methane, both in gas and in liquid form.

Polymers were filled with graphite, submicron particles or carbon nano-tubes. Experiments reveal that hydrogen environment has a major influence on both polymer structure and fillers during sliding. The sliding behaviour of these polymer composites is much improved in hydrogen compared to air. In particular, graphite and nano-particles have a remarkable effect on friction and wear, respectively.
