Package, method for storing or transporting sub-nano membrane structure, and sub-nano membrane structure

摘要

A package comprises an airtight container having an oxygen permeability of less than or equal to 15 ml/m²dMPa and water vapor permeability of less than or equal to 2 g/m²d, and a sub-nano membrane structure accommodated in the airtight container. The sub-nano membrane structure having a porous support and a sub-nano membrane. The sub-nano membrane formed on the porous support and having an average pore diameter of less than or equal to 1 nm.
