Outline Activities
Rubbers and polymeric materials are used as sealing devices of high-pressure hydrogen gas in equipments for hydrogen energy systems. For example, rubber O-ring for hydrogen gas sealing could be broken by high-pressure hydrogen exposure.
In our lab, we are going to clarify the fracture phenomenon of rubber and polymeric materials exposed to the high-pressure hydrogen gas. In order to clarify the influence of dissolved hydrogen on the fracture behavior of the materials, we have been performing thermal desorption analyses and nuclear magnetic resonance measurements of the dissolved hydrogen gas in the materials.
