Furthermore, after exposure to high-pressure hydrogen, the sample (TPU/EPDM-g-MAH/EPDM ratio 90/2/10) shows minimal hydrogen-induced damage to its internal structure, with changes in mechanical properties (tensile strength, elongation at break, and hardness) remaining within 6 %.
Results show that the hydrogen permeability of the blends (TPU/EPDM-g-MAH/EPDM ratio 90/2/10) is 1.294 × 10 −9 mol·m/ (m 2 ·s·MPa), which is 37 % lower than TPU and 87 % lower than EPDM. The blends also exhibit excellent hydrogen barrier properties compared to reported typical rubber sealing materials.
However, SEM observations in Fig. 4 revealed the presence of small hydrogen-induced blisters within TPU, possibly due to the permeation and dissolution of hydrogen gas under high-pressure hydrogen conditions, leading to reduced mechanical performance of TPU.
Thermoplastic polyurethane (TPU) is notable for its excellent properties, including corrosion resistance, weather durability, and abrasion resistance. These qualities make it advantageous for diverse sealing applications in sectors like cables, construction, and automotive industries [33, , , , , , , , , ].
Minimal hydrogen-induced damage was observed in TPU/EPDM-g-MAH/EPDM blends. In recent years, the hydrogen energy industry has been rapid growth. However, elastomeric sealing materials used in high-pressure hydrogen infrastructure still undergo significant performance degradation due to hydrogen-induced damage.
EPDM-g-MAH acts as a “bridge,” forming hydrogen bonds between its maleic anhydride groups and the amine groups in TPU, thereby enhancing interfacial interaction between TPU and EPDM. At 2 phr compatibilizer content, EPDM phases disperse more uniformly in the TPU matrix, forming smaller dispersed phases.
