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

摘要

A package (10) comprises an airtight container (20) and a sub-nano membrane structure (30). The airtight container (20) has an oxygen permeability of less than or equal to 15 ml / m2 · day · MPa and a water vapor permeability of less than or equal to 2 g / m2 · day. The sub-nano-membrane structure (30) is accommodated in the airtight container (20). The sub-nano-membrane structure (30) comprises a porous support (31) and a sub-nano-membrane (32) formed on the porous support and having an average pore diameter of less than or equal to 1 nm.
