Researchers develop improved hydrogen ion barrier films using pore-free graphene oxide membranes
Researchers from Kumamoto University and Hiroshima University have announced a significant development in hydrogen ion barrier films using graphene oxide (GO) without internal pores. This approach could be beneficial for protective coatings for various applications.
In their study, the research team successfully synthesized and developed a pore-free GO (Pf-GO) membrane with controlled oxygen functional groups. Traditionally, GO has been known for its high ionic conductivity, which made it challenging to use as an ion barrier. However, by eliminating the internal pores, the team created a material with dramatically improved hydrogen ion barrier properties.
