We report super-fast proton mobility at the 2-dimensional nanospace. The nanospace was formed at the interlayer of the polymer lamellar thin film. From the proton conductivity determined from impedance measurement and proton concentration determined by surface pressure-area-based titration curve, it was found that the proton mobility at the 2D nanospace is 100 times larger than that of bulk water. We concluded that the ability to achieve the contradictory states of high orientation and high mobility led to high proton mobility.
