This innovative approach promises significant advancements in protective coatings for various applications.

In their study, the Japanbased research team successfully synthesized and developed a thin film from a new form of graphene oxide that does not contain pores. 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.
