An active repulsive hydrogen barrier thin film (abbreviated as HBTF) was fabricated by a continuous coating process. The fabricated HBTF consists of PET substrate, positively and negatively charged polymers, nafion, and palladium/gold layer. The hydrogen gas permeability of HBTF and intermediate films was investigated using a gas permeability measurement instrument. The barrier property of grounded HBTF is much higher than that of others due to the electrochemically active repulsive mechanism. The development of HBTF could be a foundation of hydrogen barrier materials in the future.
