我们证明了单层石墨烯膜对包括氦气在内的标准气体是不可渗透的。通过在膜上施加压力差，我们测量了单层石墨烯的弹性常数和质量。这种加压石墨烯膜是世界上最薄的气球，并在两个不同的区域之间提供了一个独特的隔离屏障，只有一个原子厚。
We demonstrate that a monolayer graphene membrane is impermeable to standard gases including helium. By applying a pressure difference across the membrane, we measure both the elastic constants and the mass of a single layer of graphene. This pressurized graphene membrane is the world's thinnest balloon and provides a unique separation barrier between 2 distinct regions that is only one atom thick.
