研究了一种高取向结晶MOF纳米膜的电学性能。这种纳米膜具有低活化能和质子电导率，是MOF材料中报道的最高值之一。该研究揭示了该纳米膜具有优异性能的原因，揭示了质子在MOF材料中传输的新途径；除了MOF内部的通道外，MOF纳米晶体的表面也可以控制质子的输运。
The electrical properties of a highly oriented crystalline MOF nanofilm were studied. This nanofilm has low activation energy and a proton conductivity that is among the highest value reported for MOF materials. The study uncovered the reasons for the excellent performance of this nanofilm and revealed a new pathway for proton transport in MOF materials; besides the channels inside a MOF, the surface of the MOF nanocrystal can also dominate proton transport.
